Same issue.

When it will be fix?

Updating ASP.NET Core Runtime to 8.11 using the hosting bundle installer appears to resolve the issue.
Download .NET 8.0 (Linux, macOS, and Windows)

I updated to 8.11 and the deployments are still failing.

Upgraded from 11.1.9.1 to 12.0
Deployments no longer work.
Error message: Preliminary checks failed! Task Service Error. Binary Formatter serialization and deserialization are disabled within this application. 

The deployments is a key capability so I hope it's repaired soon

Dear all, 

We are looking into this internally. The binaryformatter is part of the TaskScheduler. We are looking into this as well with Microsoft, as it seems to be caused indeed with the move to .NET 8.
We'll keep you all updated when we have more news.

We are having the exact same issue since upgrading to 12.1.0.1 from 11.3.0.5.  None of our deployment packages seem to be working now.  Resulting in the same Preliminary checks failed!

I have had a case in for 4 days now with support but so far, it's been radio silence from them.
