Azure Static Web APP for Blazor CI build error after update to Net 5.0

Question

After updating my Blazor Webassembly project to .Net 5.0 I get an error in the CI build:

...
Microsoft (R) Build Engine version 16.8.0+126527ff1 for .NET
Copyright (C) Microsoft Corporation. All rights reserved.

Determining projects to restore...
All projects are up-to-date for restore.
Copying the minified builld styles to WWWROOT
Client -> /github/workspace/Client/bin/Release/net5.0/Client.dll
Client (Blazor output) -> /github/workspace/Client/bin/Release/net5.0/wwwroot
Optimizing assemblies for size, which may change the behavior of the app. Be sure to test after publishing. See: https://aka.ms/dotnet-illink
Compressing Blazor WebAssembly publish artifacts. This may take a while...
/tmp/oryx/platforms/dotnet/5.0.100/sdk/5.0.100/Sdks/Microsoft.NET.Sdk.BlazorWebAssembly/targets/Microsoft.NET.Sdk.BlazorWebAssembly.Current.targets(548,5): error MSB6006: "/tmp/oryx/platforms/dotnet/5.0.100" exited with code 1. [/github/workspace/Client/Client.csproj

Do anyone know why the compressing step will fail?

The .yml file:

build_and_deploy_job:
if: github.event_name == 'push' || (github.event_name == 'pull_request' && github.event.action != 'closed')
runs-on: ubuntu-latest
name: Build and Deploy Job
