@Vlad There must have been either a recursion or new bug on this in the latest build. I am not able to copy a totp code from the main screen of bitwarden. I can however as per @Crocmagnon I am still able to copy the TOTP code from the view item screen.
Also although probably related I have bitwarden set to automatically copy the TOTP code into my clipboard if I autofill a login, and this does not happen either.
