"Request failed with error: Unexpected internal error".

### Describe the bug

Hello,

Since the beginning of 2024, we've been unable to connect to our Azure VMs via the Bastion native client.
However, we haven't made any changes to our script and everything was working perfectly in 2023

We couldn't find any information on the net about this error !!!! Do you have any idea about the origin of this problem ?

Thank you for your feedback,

Sincerely,

Laurent

### Issue script & Debug output

The command "az network bastion rdp -- debug" returns the following error:
