Mac OS X goes to sleep mode when watching video or suddenly restarts

Mac OS X Catalina goes to sleep right after I start watching video/youtube. I also can hear how its fan's extensively working. It started after I installed MineCraft, but this maybe just a coincidence as it's going to sleep mode only when watching a vide. But right after it's in sleep mode when I push a power button it wakes up with no fan's noise.

I even did a recovery on the OS, the issue remains.

I looked at other SO threads but they were not helpful.

Not sure if this is Catalina's issue or not...

Just wanted to know is there's anything I should try before I decide to downgrade the OS.

UPDATE

I had to delete my answer as I discovered the issue remains. Also I noticed random restarts. After I restart I see these message in the report:

Solution 1:

I found out I was experiencing the issue ONLY when using Chrome browser, when I switched to Safari.

Then when I checked the version of the Chrome browser, I noticed it was having issues with automatic update.

Then I manually downloaded the latest version of the Chrome browser and don't have the issue anymore.
