I just installed the NCrunch_VS2019_3.26.0.1.msi and I think the feature ALT+U (open NCrunch menu) causes this issue.
Issue: the character u can not be inserted (so e.q it's not possible to type Func<T>) at least in .csproj files (I didn't tried any other project types).
If I remove 3.26.0.1 and install 3.25.0.3 the issue with the character is gone (but of course then NCrunch detects the wrong theme, at least the black theme can not be detected).
I also submitted a bug report from the NCrunch Menu.
This version has been created after I opened this ticket:

Please have a look at it, its quite frustrating when you can not to insert an u. btw keep the u key pressed does work (but adds a lot of u characters).
If you need additional infos just let me know.
