I have a database is malformed problem… And it doesn’t even say which database is malformed

[Alexey]

It could be malformed long before the update.
Please, use this method to check your databases:

All statistic was set to zero

docker run --rm -it --mount type=bind,source=$PWD,destination=/data sstc/sqlite3 find . -iname *.db -maxdepth 1 -print -exec sqlite3 '{}' 'PRAGMA INTEGRITY_CHECK;' ';' replace $PWD with the absolute path to the databases location. The storagenode must be stopped.
