AWS Backup VSS timeout


I'm trying to set up AWS Backup for EC2 instance with Windows Server 2022 and MS SQL Server, following this instruction I've done all the steps, but the on-demand backup job finishes with the message:

"Windows VSS Backup attempt failed because of timeout on VSS enabled snapshot creation"

The file "C:\Program Files\Amazon\AwsVssComponents\vsserr.log" is empty, "C:\Program Files\Amazon\AwsVssComponents\vssout.log" contains information about Shadow copies of devices and ends with the message "Snapshot creation done." There are several messages related to VSS in Windows Log, for example:

Volume Shadow Copy Service error: A critical component required by the Volume Shadow Copy service is not registered. This might happened if an error occurred during Windows setup or during installation of a Shadow Copy provider. The error returned from CoCreateInstance on class with CLSID {4baeabae-7018-43e6-8bfb-fb15aaa3a675} and Name SW_PROV is [0x80040154, Class not registered
   Obtain a callable interface for this provider
   List interfaces for all providers supporting this context
   Check If Volume Is Supported by Provider
   Add a Volume to a Shadow Copy Set

   Provider ID: {4aaed461-b7bb-4125-a906-31c79791b47d}
   Class ID: {4baeabae-7018-43e6-8bfb-fb15aaa3a675}
   Snapshot Context: 2
   Snapshot Context: 2
   Execution Context: Coordinator
   Provider ID: {00000000-0000-0000-0000-000000000000}

What else can be checked and how to fix the timeout error?
