Unknown Error in Editor (messed up viewport navigation)

When editing a level, moving meshes around, etc. sometimes when I press the right mouse button to navigate in the viewport, the “camera” starts moving backwards instead of allowing normal navigation with W S A D keys. An error message strats popping up but it’s not identified, just says “!”.

This renders version 4.11 useless for me as this happens after about 30 seconds of opening the editor.
If I close and restart the editor the problem goes away for a few more seconds.

I started getting this error in 4.11 preview (5 and 6). In 4.10 all is fine.

Thank you
