Hi, it seams that I'm experiencing the same issues as the reported upstream 
report:
https://gitlab.gnome.org/GNOME/tracker-miners/-/issues/161

tracker3 also times out on my system.
proces /usr/libexec/tracker-miner-fs-3 is using 100% of 1 cpu core.

I checked my logs and this error started appearing after installing snapshot
20210316.
Currently I'm running snapshot 20210318.

From the mentioned upstream gnome bug report this appears to be an issue with
the sqlite3 package.
And in fact in snapshot 20210316 that package got an update:
sqlite3 (3.34.1 -> 3.35.0)

A fix for sqlite3 is mentioned here:
https://mail.gnome.org/archives/distributor-list/2021-March/msg00000.html

For now I attached the report to Gnome, but perhaps it's better to attach it to
sqlite3.
