Hello,
is possible that this file have more than 35 GB?
C:\Users\Blood\AppData\LocalLow\Ludeon Studios\RimWorld by Ludeon Studios\Player.log
How strange. Mine is 3KB. And it seems to be copied in "player-prev.log" and then reset with each game start. Maybe you have some kind of debug mode on.
Did you tried to delete it? To open it with a specialized tool, (i.e. not notepad, it might not appreciate it), to see what's in it? Might be that Total Commander comes with such a tool.
