So, there's an error every second window on PC right now, after the first training session. Shame, I like the game so far.

Take a trip to the discord channel and give some context.
I run the windows version of the game all day, every day. Its the one I use the most so I would notice common errors like the one you speak of.
That leads me to believe you have some specific issues to be addressed.
Error / exception screenshots are the easiest way to get your issues fixed, so be sure to have those as well when you post about it.
