Macbook restarts after waking from sleep

**Problem:** Recently, after putting my M1 Macbook Pro to sleep (both via pressing sleep or just closing lid), whenever I wake it up after a minute or longer, instead of returning back to the screen before putting it to sleep, it just restarts (with the apple logo, sound and progress bar, then login). There is no error message after it restarts, and this happens regardless of whether laptop is charging or on battery. This is annoying because I have to reopen all my files etc. **MacOS version:** This happened both on my current version (Sequoia 15.5) and previous version (Ventura 13.2) - so I don't think this is a problem with the OS. I upgraded my OS recently to see whether it would fix the problem - it didn't. **Timing:** I don't use my macbook that much nowadays, so I can't remember when exactly it started. Maybe a few weeks ago. I think the timing might have coincided with something weird happening with my iCloud - for some reason it asked me to log in in order to use iCloud a few weeks ago, even though I've never logged out. This has never happened before. Not sure if iCloud has anything to do with it. Also after the MacOS update from Ventura to Sequoia, icons started appearing next to my files on desktop (Cloud icons, and after I downloaded them, the lower arrow icon). Otherwise, I haven't downloaded any new software recently so I don't think it's a new software download problem. **What I've already tried (but problem still persists):** - **Rebooting in safe mode:** I rebooted in Safe Mode, put the laptop to sleep and closed the lid. When I wake it after 2 minutes, the laptop restarted not in safe mode. - **Reinstalling MacOS:** Reinstalled Sequoia, problem persists. - **Switching to guest account:** Problem persists on guest account. - **Disconnecting all external devices (monitor, wireless keyboard and wireless mouse):** Problem still persisted. I've tried Googling but don't seem to find any much on this problem. I see people talking about pmset, so here's my most recent output FYI. Previously, it showed sleep prevented by cloudd like 10 times (i.e., cloudd, cloudd, cloudd...), in addition to a few other things, which was why I thought it might have something to do with iCloud. But the most recent output after restarting the computer didn't have it. **pmset -g output:**

Would really appreciate any support on this. Thanks!
