I upgraded to the latest macOS Catalina. Ever since, my MacBook keeps restarting whenever it goes into sleep mode. No indication as to why it keeps restarting. I thought that upgrading to the latest 10.15.2 would solve the issue, but it didn't. This never happened on older versions of macOS.

I'm very disappointed in the way Apple is handling software upgrades. Why so many issues all of the sudden? - My MacBook has suddenly become so slow that it's borderline unusable. And no, I don't have a virus or software slowing me down. I barely have anything installed as I use this laptop mainly for browsing the internet. My MacBook was perfectly fine and fast before upgrading to Catalina. Suddenly, there are problems that I haven't encountered before. The browsing experience has been particularly dreadful and slow.

I realize that my MacBook isn't the latest, but give me a break, I only bought it 2 years ago. Here are the specs:

MacBook (Retina, 12-inch, 2017)
1.4 GHz Dual-Core Intel Core i7
16 GB 1867 MHz LPDDR3
256 GB SSD
Intel HD Graphics 615 1536 MB

Try a SMC reset to see if that cures the restarting when sleeping. You may have a program or process that's not compatible with Catalina and causing the machine to restart. Have you checked your logs? Did you make a backup before installing Catalina? If you did, you can always go back to your older version of macOS.

Still happening. But it seems that I'm not alone: https://discussions.apple.com/thread/8567772?page=4
Some people mentioned that a logic board replacement solved their issue. However, I'm out of warranty so I'm not sure if that's really an option.

The log for this error reads:

I have a 2019 mba that restarted on its own. I also have a 2019 mbp 15" that froze on its own. Upon reboot, it returned a previous shutdown cause: -20. I booked an appointment w/ apple to troubleshoot. Very annoyed by these issues.

Did you get it sorted out?

Apple software is atrocious lately. Never had this many issues with PC's. Thinking of going back to a Windows laptop. Latest software upgrades made my MacBook 12 not only incredibly slow but also incredibly buggy. Apps constantly crash, safari constantly reloads, and it just takes forever to open or populate anything. None of this was occurring before upgrading to Catalina.

My laptop is borderline unusable.

My brand new laptop started doing this when I upgraded to Sonoma. There is some sort of historical bug here..
