Windows Server Backup stopped working after disk changes

Question

I just reconfigured the storage on one of my Hyper-V hosts, I removed 4 HDDs and added an SSD. Now Windows Server Backup stopped working, even though the HDDs formed a spanning volume which never was part of the backup.
Wbadmin.msc says "A fatal error occured. Error details: The server threw an exception".
In the Event Log I get an Error with Source: Application Error / Event ID: 1000 / Task Category: 100 and the following Details:

Faulting application name: wbengine.exe, version: 10.0.17763.1697, time stamp: 0x41bb1c2a
Faulting module name: wbengine.exe, version: 10.0.17763.1697, time stamp: 0x41bb1c2a
Exception code: 0xc0000005

Faulting process id: 0x1d00
Faulting application start time: 0x01d7771c1d6cbd17
Faulting application path: C:\Windows\system32\wbengine.exe
Faulting module path: C:\Windows\system32\wbengine.exe
Report Id: 72d77d62-28ad-4788-8078-39f11169844a
Faulting package full name:
Faulting package-relative application ID:

In wbadmin, I see that today's scheduled backup did not run and at the time of the backup, I get basically the same error as above, just with different time stamps. Running "wbadmin start backup" gives me "The server threw an exception." and again the same error-event.

I already rebooted, no luck. Any ideas of what is going on?

Hi,

As per researching, I found some similar cases and the possible solution is as below:

Open a Command Prompt (Admin) and run: wbadmin delete catalog

Or follow below steps:

1. Remove/backup the log files: C:\Windows\Logs\WindowsServerBackup
2. Uninstall the feature: Windows Backup Server
3. Restart the Server
4. Install the feature: Windows Backup Server
5. Open a Command Prompt (Admin) run: wbadmin delete catalog
6. Start the Backup Service
7. Recreate the backup Job and Services (as needed)
