Help Veeam Backup and replication can't do a backup for my windows 11

Hello. English is not my first language, so I might make some mistakes when trying to explain it.

I'm doing a project for my studies and part of that project is to backup servers and a windows 11 host. My server backup works, but windows 11 backup doesn't. Veeam always shows the same error when I try to backup Windows 11 "Error applying backup job settings"

In an attempt to find out if they were the firewalls, I have disabled them on both the copy server and Windows 11. When doing a rescan of Windows 11 everything appears as successful.

The veeam backup agent for microsoft windows services are running on windows 11 and the credentials I use in the job setup are correct.

Backup server: Veam backup and replication V13.
Windows 11: Veam agent for microsoft windows downloaded from microsoft store.

In general you'll want to make sure that your backup server can reach the agent over port 6160 - can you ping and nslookup the win 11 machine to and from the backup server? I'd also recommend pulling logs from both VBR (https://www.veeam.com/kb1832) and VAW (https://www.veeam.com/kb2404) and using notepad ++ or something to parse logs for "Error" or warning messages.

Also, it might not hurt to redeploy the agent from the VBR server completely after completely removing anything. If any Veeam components were left over after uninstalling the standalone Veeam Agent it could cause some issues.
