Failing assertion

Hi!
Got this error in error.log

2020-11-05 16:42:09 0x7ef37c66c700 InnoDB: Assertion failure in file /home/buildbot/buildbot/build/mariadb-10.4.13/storage/innobase/row/row0ins.cc line 231
InnoDB: Failing assertion: !cursor->index->is_committed()
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

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: 10.4.13-MariaDB-1:10.4.13+maria~buster-log
key_buffer_size=4294967296
read_buffer_size=131072
max_used_connections=194
max_threads=802
thread_count=139
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 5959249 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...
stack_bottom = 0x7ef37c66bcd8 thread_stack 0x40000

• • • buffer overflow detected ***: /usr/sbin/mysqld terminated

So I'm here to report it)
