How to ignore key unprotect errors

Question

My application often fails with failed to unprotect session cookie (I am using two applications with different assembly versions).

Error unprotecting the session cookie. The key {hex_key} was not found in the key ring.

or

System.InvalidOperationException: The antiforgery token could not be decrypted. ---> System.Security.Cryptography.CryptographicException: The key {hex_key} was not found in the key ring.

Antiforgery errors happen at get requests (so nothing to be protected there). How can I ignore such errors and display page for users (with new session)?

I have the same problem. It's absolutely flooding my logs and causing my app to crash. Did you manage to get to the bottom of this? – Dartmoor
