BuzzPCSOS I am experiencing this issue (and my laptop is new).
I solved this by changing the kernel scheduler (I tested with scxctl) and fixed it with rusty. (The most for my laptop)
This is so very strange... 
After 2d, I changed to the "rusty" scheduler, testing with scxctl switch -s rusty and editing /usr/share/defaults/scx_loader/config.toml to preserve the setting across reboots.
I think... it's a trouble with the flash scheduler?
