Crashing when connecting the device to Rpi

[FilipCZE]

Using Rpi3 with RpiOS - Bullseye and NanoVNA V2_2 firmware version 20201013

1. Installation completed
2. Saver launched
3. After connecting to device - CRASH

Traceback (most recent call last):
File "/home/Filip/.local/lib/python3.9/site-packages/NanoVNASaver/NanoVNASaver.py", line 517, in dataUpdated
self.windows["tdr"].updateTDR()
File "/home/Filip/.local/lib/python3.9/site-packages/NanoVNASaver/Windows/TDR.py", line 140, in updateTDR
step_response = scipy.signal.convolve(self.td, step)
AttributeError: module 'scipy' has no attribute 'signal'

... How to get rid of:
libEGL warning: DRI2: failed to authenticate ?

NanoVNA-Saver version: 0.5.4-pre
