"Signature is invalid" after SDK update

Hi
I tried to update the SDK in my WEB project, from version 2.1.1 to version 2.4.5 (latest version) and I started getting the error “Signature is invalid.”.
I validated the code of the signature generation functions, which you provide in your documentation, and everything is correct (Generate Signature in C#).
Why did this start to happen? Are there any more changes that need to be made?

The webinar I tried to join was [REDACTED] with role 0. The generated signature was “[REDACTED]”
Thanks
