mariadb crash while importing tablespace

2023-06-21  9:17:16 10 [Note] InnoDB: `filesender`.`Transfers` autoinc value set to 3051714

2023-06-21 09:17:16 0x7fd23c5e2700  InnoDB: Assertion failure in file /home/buildbot/buildbot/build/mariadb-10.3.39/storage/innobase/dict/dict0dict.cc line 1803

InnoDB: Failing assertion: table->get_ref_count() == 0

InnoDB: We intentionally generate a memory trap.

InnoDB: Submit a detailed bug report to https://jira.mariadb.org/

InnoDB: If you get repeated assertion failures or crashes, even

InnoDB: immediately after the mysqld startup, there may be

InnoDB: corruption in the InnoDB tablespace. Please refer to

InnoDB: https://mariadb.com/kb/en/library/innodb-recovery-modes/

InnoDB: about forcing recovery.

230621  9:17:16 [ERROR] mysqld got signal 6 ;

This could be because you hit a bug. It is also possible that this binary

or one of the libraries it was linked against is corrupt, improperly built,

or misconfigured. This error can also be caused by malfunctioning hardware.

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: 10.3.39-MariaDB-1:10.3.39+maria~ubu2004 source revision: ca001cf2048f0152689e1895e2dc15486dd0b1af

key_buffer_size=134217728

read_buffer_size=2097152

max_used_connections=2

max_threads=102

thread_count=6

It is possible that mysqld could use up to

key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 760042 K  bytes of memory

Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out

where mysqld died. If you see no messages after this, something went

terribly wrong...
