Can't start Specter Desktop

I'm trying to run Specter Desktop for the first time, but it can't start and I can't figure out what could be the reason.
I'm on Ubuntu 22.04 and I downloaded Specter Desktop 2.0.1.
I just double click on **Specter-2.0.1.AppImage**, it downloads file from Github and then returns the following error:


Here is the log:

```

The process seems to hang on HWI initialization, but I never plugged any HW wallet...
So, what could be wrong?

Start by reproducing the launch on Ubuntu 22.04 with Specter-2.0.1.AppImage and inspect the provided log, especially the HWI initialization and specterd exit. Done means identifying the cause of the startup failure and confirming that Specter Desktop starts successfully or documenting the required resolution.
