Try to find under /www/backup/panel/ latest compressed files Then extract out to find the data/default.db The file cover /www/server/panel/data/default.db The restart the panel again whether can solve?
For example, the decompressed file is stored in /www/backup/panel/2023-08-30/data/default.db

cp /www/server/panel/data/default.db /www/server/panel/data/default.db_bak
cd /www/backup/panel/
unzip 2023-08-30.zip
cp 2023-08-30/data/default.db /www/server/panel/data/default.db
bt restart
