After Login: Unable to run a hybrid app on a desktop

Hey everyone,

I am currently trying to deploy a 7.3.0 app. It's on a Linux platform ( on premise).

If i run my app localy from my modeler it works fine without any problems.
I unpacked the deployment package on the Linux platform and the app also starts without any errors. But after I try to logging to the app it gives the Message:

Unable to run a hybrid app on a desktop

After that i only have the option on clicking on "Ok" and then the screen turns white and nothing works. No layout or anything.
