Loading UI error XML files

[Gov_mule]

I had to reinstall after a fresh installation of Win11.
when I change the UI I get an error XML files with current EverQuest files.

I tried several old standby UI like duxaui and some new (to me)ones by drakah and sakui all fail with the same message. Furthermore, I set the compatibility mode in property to win XP.

No change, do I need to rerun the patch or something?

I searched the forum but did not find anything helpful
I did run dgVoodoo as well.

Thanks in advance
