Simulate with dymola python package not possible - dsres.mat not found

I tried simulating a simple model of my library with the use of python:

dymola.translateModel("path.to.model")

output = dymola.simulateExtendedModel('path.to.model')
log = dymola.getLastErrorLog()
print(log)
print(output)

Output is:

Translate = True

output =

Failed
Not possible to open file "dsres.mat": No such file or directory
 = false, {}

[False, []]

Seems like the model gets translated just fine, but doesn't finish/start simulating.

Edit:

• Licence status is correct
• Using DymolaInterface(showwindow=False) shows that the correct model and all its dependecies have been loaded
• Quite a lot of warnings (F.e. wrong unit used), but the model simulates just fine with dymola
