Unable to remove S3-compatible storage - locked by running task configuration database resynchronize

[BostjanUNIJA]

We would like to remove S3-Compatible backup repository.
There are none backup jobs, backup copy jobs linked to this backup repositories anymore.
Rebooting VBR server doesn't help.
If we wish to remove repository we receive an error:
"unable to remove s3-compatible repository locked by running task configuration database resynchronize"
How can we (forcly) remove this repository from VBR configuration?

The best course of actions will be to reach out to the support team and request them to remove outdated references from the backup server database. Thanks!
