Platform: Windows
Distribution: Steam
It could be a problem with one of the mods you have installed, not something you have done (unless you edited the code), I would either disable any mods you recently installed or see if a newer version is available.
Trying using ‘CheatMod Revived’ on the Steam Workshop instead of CheatMod by kristof1104, this could solve your problem if the CheatMod is causing it.
