Installation or removing bitwarden Edge extension - breaks windows authentication

We have several windows 11 computers with Edge and the bitwarden plugins.

Several users with diacritic marks (umlauts, ä,ö,ü) have problems with windows authentication against IIS Server.
I had a lot of tests and installation and could trace down the problem to the bitwarden extension for Edge (2024.10.0)

A clean Windows 11 installation works fine, as soon as i install the bitwarden Edge externsion, the integrated authentication Fails for the previous working IIS Server.

Does anyone know, what breaks the integrated Windows authentication?
