Cannot loop through more than 6 conditions

OS (e.g. Win10): Win 10
PsychoPy version (e.g. 1.84.x): v2022.2.4
Standard Standalone? (y/n) If not then what?: y

What are you trying to achieve?:
I am trying to run 4 videos (3s, mp4) on a 2x2 matrix every trial followed up with a questions trial.

What did you try to make it work?:
I created a .xlsx conditions file to loop through different videos randomly for each trial. (I added 3 types of videos for each trial, using the 3rd one twice in the experiment)

What specifically went wrong when you tried that?:
Everything works smoothly when I only run with 6 conditions from the condition file. However when I try to increase the conditions psychopy crashes (the last trial page gets stuck on the screen and I have to quit by ending the program). Weirdly I am not getting any error messages either. I would like to be able to run it with at least 15 conditions or such (around 50 videos).

I tried different things to solve the problem where non of it seems to work. Any help would be hugely appreciated! Thank you
