You will probably have to wait for Manfred to look into it. He is on holiday currently until the beginning of September.

Did you compile from source or downloaded the package?

I downloaded and installed the package : Bisq-64bit-0.5.3.deb  
Strange thing is, the application was working fine until yesterday… Maybe a system update modified something ?

I tried running the application from a test user/new profile, same thing happened : same error message, and the app window displays nothing.  
Waiting

It is possible that the system update messed it up. You should be able to pick the previous version of your system on boot. That could be a temporary solution.
