Some kind of error came out of nowhere, I can't use the character anymore!

the error occurs when I select SHIN GOREN as a character, it says the following

ERROR - these files are missing:
## NOTICE: all of thge following paths are being read from "GokaFlame.tscn".
##godot automatically generates all these paths depending on their location in the FileSystem tab.
res://_NokArchmage/characters/archmage/projectiles/Witherflame.gd

(got prints)



I had no problems with characters since update 1.8, Shin Goren was one of them, after a while, our boy NOK fixed the problem, I reinstalled the character and everything was fixed, and out of nowhere, this happened, SHIN GOREN was working perfectly before despite having only 1 hit due to 1.8,all other 41 characters look ok, including other characters made by NOK that I have installed
