After running Windows update on my NPS server where MFA extension is installed users are unable to enter MFA numbers.
In AzureMfa -> AuthZ -> AuthZOptCh log I get this log Event ID 1 NPS Extension for Azure MFA: CID: xxxx : Challenge requested in Authentication Ext for User user@domain.local with state 300e3266-10c5-4eda-a576-a6cc5fef6374
Users receive 3 MFA sms with different numbers but are not able to type the numbers.
MFA is used with VPN from Check Point

NPS MFA plugin stopped working since July 2024 cumulative update, didn't work with August, nor September. As a workaround, NPS servers had to be reverted to July CU.
