The Arcade specific fix for the VS 22 Images didn't seem to fix the issue.

https://github.com/dotnet/sdk/pull/51558/files From what I observed, the PR I made fixed the issue, but it got overwritten by Arcade. Arcade tried to fix it in a different way but the issue is manifesting here, despite the fix flowing. I've pinged FR to see if they're willing to apply my fix centrally or see why the Arcade fix isn't working. This is definitely a challenging one to tackle 😁
