I was having this issue initially. I was able to resolve them after I upgraded my project to .NET Aspire 9.0 (RC 1) - you can see the upgrade guide here

@kylejuliandev this seems to fix the frequency of the errors, but the error still persists.

joperezr commented 14 hours ago

We released .NET Aspire 9.0.0 earlier today, would you be able to update to that stable version and see if the issue persists?
