I have a 2 display setup. I move some Safari windows to one screen. After waking up from sleep, all windows are on one screen and the second is empty. This is on an M1 mini.
New Mac Studio (currently 12.3.1), with 2 Dell P2715Q screens, both attached with USB-C -> mDP cables. Had a session with Apple Support, they ran through every debugging thing they could think of, no fix. Apple Support said it is a bug and they are working on it. So... one day we will see it fixed I guess. Until then, there is Moom to the rescue. If you want to try, I got Apples attention by tweeting to their Twitter AppleSupport channel.
A couple of things to note. Moom does work for me! But, I needed to do an extra to get it to work. After installing Moom, and setting up my application windows they way I want, I created a snapshot in Moom. Then, I updated the snapshot while holding the option key down. After doing this, I can now quickly reset the position of my apps to the secondary screen with my shortcut. Hope this helps someone else.
The only app that seems to stay where they belong (it it is not on the main screen) is Reminders of all things. I don't know of any other app that wants to control the screen. I'm a developer so it's mostly different IDEs and programming tools, couple of Electron based apps (ex Slack) and then standard Apple apps (Safari, Music, Calendar).
There does seem to be a time aspect to this. Everything stays in place if it only sleeps for an hour or so (ex if I go to lunch) but over night things definitely get scrambled.
I have the same problem (two external 4k dells on a 14" m1 map max); something that may help - I find if I close the lid of the mpb before sleeping, then on wake the two dells (and windows on them) will be still arranged correctly.
I seriously doubt Apple developers are creeping around these boards to work on new bugs. The only way they will is enough people file bug reports.
Once enough are received, one would think that a company that is interested in being eco friendly would not want the work around to be never let their computers sleep and waste all that electricity.
Fill out bug reports to bring it to their attention otherwise we are stuck with never letting our machines sleep and increasing our carbon footprint.
okay. this makes so much sense as to why the windows fail. also, it seems like it's going yo be hard for apple to fix. anyway, i have just one minor addition. after wake up, you can get all the windows back with finder->show all. at least that works for me. now all i have to do is remember to hide others before sleep mode. thank you.
I have the same thing. 2 ASUS (PA248, PA278QV) displays, 5 spaces. Mac Studio 12.3.1.
All the Windows for all applications are gathered onto the monitor with the Dock, in all spaces.
My systems is NOT sleeping. It happens when the screensaver is activated for a while. That is, if I do Command-Control-Q and login again, it's OK. If I go away for a while, it's not.
I, too, have lots and lots of windows. The thought of having to deal with this for any length of time is extremely frustrating.
I know it's not while sleeping because:

Big Sur initially did this exact same thing. I was connecting with Apple Support multiple times on it. Finally after one of the later updates the issue resolved and ever since was solid. Then Monterrey came along and here we go again. Exactly the same issue the Big Sur had initially. One would think and hope that Apple would have carried that solution over between operating systems.
I have tried the link's method (by creating calibrated color profile) but still not works. The app's windows still goes everywhere after sleep wakeup.
Setup:
Macbook Pro 16" M1 Max + 2 x Acer VG280K (connected by USBc + HDMI).
Can Apple please do fix this little bug. This is killing macbook productivity everytime when we wake up from sleep, need to reorganise the windows in every desktop.
Can you forward it to devs instead of giving this generic reply? It clearly is a bug.
The bug is still happening with Monterey 12.1. Please bump the issue up!

has anyone reported this defect to apple? should we all report this defect to apple?
We can try and hope for something to happen.
the best solution so far is the hide others. it works most of the time.
Since you just bought a new machine, I highly recommend that you call support. The more people that do, the more the chance they'll fix this.
early on, there was a workaround posted using finder and hide others. it works pretty well. not as well as an actual solution though
Just got a new MBP 14 and see the same issue. I've assigned certain apps to certain displays (2 external and the one on the laptop itself) but every time I wake the laptop most have moved to Display 1. Running 12.0.1 and running the 2 external (HDMI) monitors through a Thunderbolt 3 hub.
Same thing too, using 2 external LG 4K monitors via USB-C on a 2019 16" MacBook Pro. When using Big Sur all was fine. Was hoping that 12.1 would fix it but that was false hope :-(
After upgrading same issue as others are mentioning here: windows are re-appearing randomly on the three screens after returning from sleep (which is several times a day). Not only that, every now and then MacOS also "forgets" that those 2 external monitors do not support the HDR setting (different story) and the setting is turned back on.
Thinking about downgrading to Big Sur since this is really annoying
Monterey seems to not remember which display should show which windows after sleep wakeup
