My recommendation would be to make sure your mods are compatible with the current version of SPT and see if the same error persists or not. Incompatible mods is a very common issue for having issues so it's always best to double check or triple check that they are compatible.
Hope this helps!
Thank you. I tried uninstalling mods one after one. And in that process i found what mod made my game give an error.
But thank you so much
