Thanks very much, Gouki! It's all about the Tactical Action mod. The error disappeared, but for this I had to put it back. Indeed, Tactical Action was in the modpack I played earlier. I didn't think there would be any traces left after deleting the mod collection. Unfortunately, a complete reinstallation did not help get rid of the trouble. I also deleted the [7DaysToDie] folders in AppData\LocalLow & Roaming, but that didn't seem to be enough. After starting the reinstalled game, the error did not go away. Tell me, please, what else needs to be removed so that there are no traces of the previous game? Thanks again for the advice and sorry for the google translate.
