Macbook Pro 2020 (M1) crashes every time it goes to sleep

I encourage you to create a time machine backup while you still can.

Time Machine saves, and can re-create, ANY Moment in time for which it still holds backup files.

Example: a user posted that they had installed software that messed up their files. it was installed mid last week. They had done an ordinary restore to recover, but that restored to yesterday, and the problem was still there. 

Readers were able to guide them to Time Machine.APP (not to be confused with Time machine preferences). This allowed them to look at the state of the major folder involved, back in time through each previous backup, until right BEFORE the bad software was added -- mid last week-- and restore as of that moment. They were thrilled.

thanks, that just the essence. That's a watchdog timer fired because the Registry was reserved and never released.

Got any older ones, or were all lost when you did the re-install?

aside: the AAAAAAAA stuff is a dump, where, in the old days, what used to be shown as hexadecimal values (4 bits per symbol, 1 through 9 and A through F). Now six bits per symbol are encoded onto the Uppercase and lowercase alphabet and numerals plus plus-sign and slash to make a total of 64 symbols. It may be called Base-64 encoding.

you have one crash report of a vanishingly rare occurrence. That is more suggestive of a hardware problem than anything else.

If you do not have a recent local, disk-based backup, your computer is like a ticking Time bomb. You are only one disk failure, one crazy software, or one "oops" away from losing EVERYTHING! Drives do not last forever. It is not a question of IF it will fail, only WHEN it will fail. In addition, you never know when crazy software or Pilot Error throws away far more than you intended.

If you are using another direct-to-disk backup method that you prefer, and you currently have a recent disk-based backup, that is great. If not, you should consider using Built-in Time Machine. Take steps to acquire an external drive as soon as possible. If you buy one, a drive 2 to 3 times or larger than your boot drive is preferable for long term trouble-free operation. Do not pay extra for a drive that is fast.  (You can get by for a while with a "found" smaller drive if necessary, but it will eventually become annoying).

Attach your external drive and use

System preferences > Time machine ...

... to turn on Time Machine and specify what drive to store your Backups on.  It may ask to initialize the new drive, and that is as expected. APFS format is default format if running MacOS 11 Big Sur or later.

Time machine works quietly and automatically in the background, without interrupting your regular work, and only saves the incremental changes (after the first full backup). Time machine backs up your machine — including every connected drive that is in a Mac compatible format. it can not back up Windows format drives.

Time Machine's "claim to fame" is that it is the backup that gets done. It does not ruin performance of the rest of the computer while doing its backup operations. You do not have to set aside a "Special Time" when you only do backups. When you need it, your Time machine Backup is much more likely to be there.

How to use Time Machine to Backup or Restore your Mac:

Back up your Mac with Time Machine - Apple Support

Kernel Panic Reports are stored in the Folder at:

/Library/Logs/DiagnosticReports

If you copy and paste that string into:

Finder > Go menu > Go to Folder

it will take you to the Folder where those reports are stored.

Kernel panic reports are named with Date&Time and start or end in ‘panic’

If you find one, please post the entire report here, by using the “additional text” Icon in the reply footer (looks like a paper with writing).

Please don’t post more about 20 lines of any other types of reports — they are interminable, and any information useful for this purpose is on the first screenful.

If you post your kernel panic here in its entirety, using the additional text icon in the reply footer, we do have some Readers (typically with developer background) who can attempt to interpret those panic reports. Even if no clear symptom emerges, this can still save a step if you DO need to contact Apple support later, because Apple Support specialists can read the panic reports you posted here, if you tell them what discussion or what Avatar.

just include the part up to where its starts naming all the routines and gets really verbose.

Forum policies require that everything related be available forever on the forums, and must be under forum control, so posted on another server is not a solution.

¿what is the date of your most recent backup, and by what method?

Have you run the diagnostic? it does not generally find more than GROSS errors, but you never know.
