This error indicates that port 42427 is already in use on this system. Possibly some Cryptomator instance running on a different user account?

You can go into Cryptomator's settings and choose a different port, though:

(copied answer from #1853 with old error code)

[efaivre]

What number should I write in the WebDAV port field? any number?

[overheadhunter]

Anything between 1024 and 65535 should work. It must not already be taken. For ports between 49152 - 65535 you should expect it to stop working any other day, since ports in this range can be assigned by the system automatically.
