InnoDB: Failing assertion: btr_page_get_prev(next_page) == btr_pcur_get_block(cursor)->page.id.page_no()
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

200622 16:32:51 [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-bugsWe 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-log
key_buffer_size=536870912
read_buffer_size=2097152
max_used_connections=7
max_threads=302
thread_count=14
It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 2387206 K  bytes of memory
Hope that's ok; if not, decrease some variables in the equation.Thread pointer: 0x7f5c780009a8
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...
