Db abnormal restart with signal 11

Our side have encountered mariadb abnormal restart, our side used mariadb 10.6.19 the details log is as below: Anyone has encountered and any fix for this, seems alter sequence can trigger this event?

241111 16:11:42 [ERROR] mysqld got signal 11 ; Sorry, we probably made a mistake, and this is a bug.

Your assistance in bug reporting will enable us to fix this for the next release. To report this bug, see https://mariadb.com/kb/en/reporting-bugs

We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail.

Server version: 10.6.19-MariaDB-log source revision: 8f020508c87461bbeee551c3001acac56d506ae7 key_buffer_size=20971520 read_buffer_size=1048576 max_used_connections=639 max_threads=65546 thread_count=258 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 201589180 K bytes of memory Hope that's ok; if not, decrease some variables in the equation.
