Segmentation Fault on Ubuntu 20.04 with libsmu-1.0.3-ubuntu-20.04-amd64.deb

I've compiled pixelpulse2 according to Readme.md and installed libsmu-1.0.3-ubuntu-20.04-amd64.deb.
When I'm starting the program the GUI appears for a short time, then the software crashes with a segmentation fault. This is the stdout:

Today I noticed that pixelpulse2 works with a version od libsmu I compiled myself. After some thought it seems that might be caused by plugging the adalm1000 out and in again. If this is true it might be a good idea to add a note to the installation instructions.

I had plugged in the board before installing and compiling the software. I encountered the segmentation fault problems before plugging the board out and in again.

Hi,

We will look into reproducing this, check out what's causing it and come back with some answers as soon as possible.

Thank you!

Exact same issue here on fedora 35 after compiling master branches of smu and pixelpulse myself
