If systemd doesn't recognize that service has started, that mean probably pid file has other location than previously. You can check what systemd is doing via strace:
strace -s 1024 systemctl start dovecot
strace doestn't show anything about opening a pid file.
There's a few repeated of these:

And then it ends in a loop with a failing
recvmsg(3, {msg_namelen=0}, MSG_DONTWAIT|MSG_CMSG_CLOEXEC) = -1 EAGAIN (Die Ressource ist zur Zeit nicht verfügbar)
The strange thing is, that strace mentions then even php7.4-fpm. Which should have nothing to do with the systemctl start dovecot?
Anyone here has a bullseye system where this works? Maybe I also should report this to the Debian BTS.
