Broken Pages in DB

Hi,
we are using Nexus Storage manager. After a crash of the the Nexus application, the storage has been switched to readonly mode. The storage has a size of about 400 GB.
Here is the error output
2023-08-29 09:40:41,146-0400 WARN [qtp2028174808-544] hudson org.sonatype.nexus.repository.httpbridge.internal.ViewServlet - Failure servicing: GET /nexus/content/groups/npm-public/bootstrap

We also tried to export the DB but that again threw lots of errors. And we tried to rebuild the index which again threw various errors.

Does anybody know how to fix this issue?

If you need more info, I am happy to provide it.
Nexus version: 3.51.0-01

Thank you in advance for your help!
