I'm gonna piggyback off of this as it's the latest issue of this type. What I assume is happening is that there's an issue with the implementation of android's full disk encryption. Specifically, to avoid reencrypting the entire device every time you swap your pin, it's only used to re-encrypt a master key which is then used to decrypt the storage itself. TWRP asking for password is proper functionality, as you need one, the decrypted master key specifically. In order to obtain that you need to first decrypt it with your pin, which means that TWRP needs to implement pin decryption of the master key. I am unsure of the actual status of this feature.

@meganukebmp this continues happening now with the latest TWRP - even if no device encryption is enabled in android 10. I assume that the pin being used to unlock the phone somehow does a 'light' encryption which TWRP cannot properly use.
