NR Fails to start server

General

I installed NR on Windows 11 and run it successfully for the first time. After installing and reinstalling couple of modules the NR does not start any more. I got following errors:

Clearly some node you installed is problematic. What nodes did you install?

I installed node-red-contrib-uibuilder, node-red-dashboard, and one of the opcua ones. Since then I removed the modules, that did not help, so then I removed node-red. cleared cache, deleted files from C:\Users\Art.node-red folder and C:\Users\CZV3JP\AppData\Roaming\npm, and reinstalled node-red. I guess these were not proper steps, so I ended up with node-red not starting.
