The h2 database has failed, and is likely to be corrupted badly enough to be unrecoverable.

I would

• Rebuild using the last backup you took
• Drop everything else you are doing and plan to move to a supported database as a matter of urgency
• (Ideally, build a new confluence with a supported database and restore your backup into there instead of h2)
