|My untouched React-Redux/ASPCore project went from working fine to getting this error.
I upgraded all core components to 3.1.16 but still have the issue.
Two temporary solutions work:
1. It works if I disable SSL, but of course that is not a solution. , but want to stay with core so can not update to .NET 5 as one solution suggested.
2. If i uninstall KB5003637, the error goes away and everything works fine. However, I have to keep uninstalling the security patch after other updates and it is annoying.
Hopefully someone has found a better solution.
I have read that upgrading to .NET 5 solves it, but I need to stay on Core.
