PicoScope 7 Software

All devices are shown as unsupported
Hello,
I'm using picoscope 7 on NixOS Linux to connect to our various Picoscopes. In this case a 4000a model, but I've also tested with 3000 and 5000 models. This used to work without problems but since some update all scopes are shown as unsupported and I can only select the Demo device.
I'm aware that I cannot expect the same level of support being on a not oficially supported distribution, but if anyone at Picotech or the community has any Ideas how to get to the root of this problem it would help me a lot. I've already done quite some research on my own, but without knowing the internals of the picoscope application it's a bit difficult. I've attached screenshots of the problem and my findings so far below.
I've verified using strace, that the correct driver (`libps4000a.so`) is actually found and loaded. There is very little information as to why the device is unsupported, no errors on the console or anything else. Using the device from c++ code by linking libps4000a.so works as expected.
The device as shown by lsusb:
installed package versions:
Verifying with strace that the dynamic library gets found.
Any idea as to how I could further analyze the problem, enable further logging or maybe some information as to what could cause a detected device to be shown as unsupported?
PS: In general it would be helpful for packaging and reproduction of earlier behavior if the repository would keep older versions of the software available and not only the latest versions. I'm pretty sure that it worked previously, but there might also be some other change on the system...
