Describe the bug

Hi,

So, I've created myself a VM using the Ubuntu 64-bit ARM Server 22.04.3 iso image. I've configured it as a agent to use with Azure Dev Ops. I've installed the azurecli and bicep but when attempting to run az bicep version i get the error detailed below.

Related command

Hi @darren221980
Find similar issue #18177.

Issue title	Failure during 'az bicep upgrade'
Create time	2021-05-21
Comment number	4

Possible solution:
The error message in the new issue is similar to the error message in the old issue, which is related to permission denied when accessing the bicep binary. In the old issue, the user had to manually delete the .azure folder and do a fresh install of azure-cli and bicep to solve the issue. Therefore, I suggest trying the same solution for the new issue. Manually delete the .azure folder and do a fresh install of azure-cli and bicep. This should solve the issue.

Please confirm if this resolves your issue.

Unfortunately this didn't fix it for me. I've tried removing the .azure folder and then done a fresh install of azure-cli and bicep a few times now with the same result.
