InnoDB corrupts the database tables

I have been working with MariaDB since last November; first with 10.6, & now with 10.5.16. I use MariaDB as the internal server for DigiKam photo management software. I was advised by DigiKam support that MariaDB 10.6 was not working with DigiKam 7.4. I read that MariaDB 10.7 was less stable than 10.6 & it was recommended to use 10.5. The full crash of MariaDB in early April caused DigiKam to fail to launch. I managed to completely remove MariaDB 10.6 & do a fresh install of 10.5.16. But all the additions to the database done between Nov & April were lost. Early June I was able to recover from the crash and re-edit the database. It appeared as though 10.5.16 was working well with DigiKam 7.6.0. Today it has crashed again. DigiKam will not launch. The error log says to report this as a bug. So here it is. Please see the attached error logs.

I'm working with Win 10 Pro 64-bit.
