Zero Division Error (__init__.py line 294)

Animatic Video Sequencer 0.8.8 bugreport
This happens in Blender versions 3.6.9. In version 4.0.2 - it just says "No files to load!" and I'm not sure where to go from there. It worked before in 3.6 properly, opening a folder browser for me to add.

3.6 Bug - Trying to add the image sequence folder via sequencer menu as usual produces this result on Windows 10, Blender 3.6.9 - then it jumps to frame 1540 in VSE and produces this error:
"Python: Traceback (most recent call last)
in "init.py" line 294, in modal f_average = int(sum_frames / len(self.avg_frame_list))

ZeroDivisionError: division by zero"

I can kind of get that it's a fixable problem, if I just google it there seem to be solutions, but feel like I might break it if I go fix it myself. Already tried something and did a clean install after because rewriting the file was causing more issues for me.
