Using version 5.0.2 after deleting previous versions inc the language files.

I need the steamid64 of the player/s where this issue happens and possibly the configuration file (without the API key ofc).

Same here, i can provide config and steamids of the players on my discord crash#0002

After upgrading to 5.0.3 i have not had any reoccurence of this error yet.
