Thanks for the report.

The log shows this relevant line:

Bun: Skipping global update detection because C:\Users\toto.bun\install\global is missing package.json

UniGetUI is detecting the installed Bun packages, but package search and update detection do not appear to be working correctly in this setup.

We'll review the Bun implementation and post an update here once we have more information.
