Try running the game first. Close it down. Then try running the editor. This is what works for me most times.
ok, so I removed all mods from the DLC folder in the game files of TSW 6. Sadly that did not fix the problem I am having . Additionally, I fully deinstalled and then reinstalled TSW 6 and the TSW Editor and that also did not solve my issue
Yes, same problem here...funny thing, the editor opened once after accidentally double-clicking on my .uproject file, but then the editor doesn't recognized the 'my projects'-directory as a valid directory for the editor...didn't list it/completely ignored it.
