nextDNS 1.12.1 on Linux broken

Just updated nextDNS client on Linux Mint from 1.10 to 1.12.1 and rebooted and it stopped working:

~$ nextdns status
not installed

After a "nextdns restart" it seems to be running but the log looks like this:

:~$ nextdns log

I really wish you would test your new versions a little bit more before release ...
