Help needed Unbound made my router unusable

[Simaryp]

I only wanted to add quickly a bad domain to the blocklist and added .*\.srvtrck.com to the list. After Applying it took long time. This is in my experience not unsual. But after really long time it didn't recover. So I wanted to check whats going on and logged in by accessing via the IP the opnsense machine. Unfortunately 99% ist not working. No dashboard no access to anything. So I thought I reboot the router. But with the same result.

I didn't remember whether I had ssh activated so I gave that a try, but no response. What can I do?

I managed to get the backup running via console.

But if anybody has an idea how to set up the blocking correctly I woupd be really happy.
