[MacOS BigSur] oathtool: base32 decoding failed: Base32 string is invalid

[ckzgraphics]

Hello team - I have set up lazy-connect on my system. I copy the TOTP/key from Google Auth Chrome Extension and the VPN list is imported successfully. However, when I try to connect to a VPN from the list it throws error -

oathtool: base32 decoding failed: Base32 string is invalid
Error: Unable to generate otp using oathtool.

What can I do here?

P.S- This used to work on MacOS Catalina. But once updated to BigSur this is not working.
