Description
Unable to restore Maria db database from backup file. Tried all 6 recovery modes but the result is same.

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: 10.3.24-MariaDB
key_buffer_size=134217728
read_buffer_size=131072
max_used_connections=0
max_threads=2002
thread_count=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 4532509 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

How was the backup created and prepared?
Is the log excerpt from before attempting a restart with innodb_force_recovery=6? The following message is already a sign of trouble:
2021-10-02 1:22:15 0 [Note] InnoDB: The log sequence number 98679815448 in the system tablespace does not match the log sequence number 98679815692 in the ib_logfiles!
The assertion failure signals that the next-page and previous-page links between two sibling pages in an index tree are inconsistent. Given that innodb_force_recovery=6 was mentioned, a plausible explanation is that no redo log was applied to one of the pages, and thus the pages correspond to different logical times.
Is this repeatable? Does CHECK TABLE report any errors on the server from which the backup is being made?
