1. I'm curious about screensaver being involved here. Check your screen saver settings. Could the default..OOTB screensaver settings in 20.1 be different than the 19 mint varieties? I've always set mine to off as I couldn't care any less about a screen saver.
2. Check your power settings is it set to power saver? cpupower-gui can be your best friend on a side note.

3. I wonder if the problem has something to do with the laptop going sleep and not waking up properly and possibly involving the gpu driver you have.
Some have reported the Radeon driver ( meaning you went to amd.com and followed their instructions on downloading and installing their Linux driver..instead of just leaving the original driver as it built into the Kernel). instead of the regular " amdgpu" driver as the source of the problem. The machine wakes up properly, but the video driver doesn't load or do the normal..things all the way and that's why the screen is blank and the system almost completely unresponsive.
I never install drivers on my LM 20.1 Cinnamon machine from amd for my rx 580 vid card as there has never been a need . Mine shows

3. One thing that is most often mentioned is a kernel update away from 5.4.whatever-whatever to 5.8.x.-x . Most often if the kernel s the problem, going to 5.8
will fix it as that kernel is said to contain many code patches/fixes.
I always recommend taking a Time Shift snapshot backup before doing major kernel updates, but I've never heard of anyone having problems when updating from 5.4.x-x to 5.8 varieties done through the Update Manager built into Linux Mint
