hello, thank you for attaching the crashlogs. Can you please also send your DataStore folder and Player Logs mentioned here: How to Properly Report Bugs!
If you have any more details about the crash that occurred when you enchanted an item, that would be helpful. Did you crash the moment you hit enchant? Did you end up getting the weapon enchanted, if so which enchants are on that weapon.
and now crashing at every retailer, is this on every interaction with a vendor? only while doing certain things?
