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.
Additional Info - Using Monterey 12.3.1 so it's still happening on the most recent update.
Ditto!
Now THAT is a great idea!
Apple quality has really tanked since Steve Jobs died. And of course, here we sit not being able to get a trivial bug fixed. Kind of shameful.
I just tried the "finder and hide others" approach for two days, sometimes it works, sometimes windows still go out of place (i.e. some windows stayed sometimes, other times still all out of places).
Updated to Monterey 12.4 today. Was hopeful this issue would be fixed... but no. Come on Apple, you're better than this... aren't you? This is really annoying... :(
Thanks for sharing this, but unfortunately it didn't work for me. Still getting windows positioned in the left bottom corner after waking up the Mac.
I actually tried this tutorial in the first place, to calibrate external monitors, but does not work as well.
Tried this today. No luck also.
Not fixed here in 12.5 :(

Try reading my 2 previous comments. I know for a fact the procedures work on my 3 Eizo 32" monitors.
You might find the solution will work for your Samsung monitor too.
Same behavior, just submitted Product Feedback - Apple for this.

1st gen M1 MBP - Acer Monitor connected via HDMI thru USB-C hub. No equipment changes. No settings changes. Updated from Big Sur to Monterey 12.1 and now it reassigns my carefully placed windows every time it goes to sleep.
I am also having same issue ever since updating to Monterey on my M1 Mini. Wasn't an issue with Big Sur.
FWIW I have filed a bug report (recommend others do the same), and typing `pmset noidle &` in a terminal window prevents the mac from going to sleep so it's less annoying.
Monterey seems to not remember which display should show which windows after sleep wakeup
