yes correct this log is far to be clean , F is a warning message meaning Moss get freezes (externals ones) similar but shorter to “Moss was inactive for” as it appears too in log.
it may happen if PC is under stress for a short time or if PC is too low end for the game, but in this case when it happens the game experience is of course highly affected. if the only victim is the Moss process , it means Moss is the target.
Generic game choice also should generate a screen each minute (it’s a medium value to make the exact screen time unpredictable), which is far to be the case in your log.
and finally the game selected should be “R6” and not “generic”
