Muon checks the modification time of `/var/lib/apt-xapian-index/update-timestamp`, `/var/lib/dpkg/status` and `/var/cache/apt/pkgcache.bin`. Only if the timestamp of the index is older than any of the other two, then the index is rebuilt.
Something is updating/touching files more often than expected. Maybe unattended upgrades?
Could you please run in a shell
sudo update-apt-xapian-index --force
just to see if the index is built correctly or it fails somewhere.
