We had the same error message

Antiforgery token validation failed. The antiforgery token could not be decrypted.

on an app which runs on disributed instances, we decreased the instance to one then problem is solved. This solution may save hours of someone one day.

We had similar issue today. We were able to resolve by persisting data protection keys to file system.

services.AddDataProtection()
        .PersistKeysToFileSystem(new DirectoryInfo(@"\\UNC-PATH"));
