Cryptomator port out of range

Crypotator will not start any more suddenly, so I can’t access my files.

Cryptomator 1.3.2 on Linux 4.10.0-42-generic (amd64) Mint

WARN org.cryptomator.launcher.InterProcessCommunicator - System property cryptomator.ipcPortPath not set.

openjdk version "1.8.0_151"

OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode)

How can I fix this? (new install did not help)
