I have the same problem: Kodi crashes regularly, looks like when it tries to update some sqlite3 database. In the following crashlog Kodi crashed after I stopped viewing a Youtube video (with plugin.video.youtube). Tested with LibreELEC-RPi4.arm-11.0-nightly-20220215-f42fa56.tar
Note that the SEGFAULT occurs in /usr/lib/libpython3.9.so.1.0 and this behaviour started with the switch from python 3.8.x to 3.9.x (#6227)
I have a build with DEBUG=Python3,kodi and can reproduce the crash with that.
