Windows update KB5003637 has caused my ReactJS/C# .NetCore app to ERR_HTTP2_PROTOCOL_ERROR 200
-
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:
-
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.
-
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.

.NET 5 is .NET core. It's not the .NET Framework, rather it is the combination of .NET Core and the .NET framework into one single entity.
