Mouse-click on Staircase Loop Causes Error

OS (e.g. Win10): MacOS Monterey (Macbook Pro M1)
PsychoPy version (e.g. 1.84.x): 2023.1.3
Standard Standalone? (y/n) YES If not then what?:
What are you trying to achieve?:
I am trying to click on a loop in the builder.

What did you try to make it work?:
I clicked on it with the mouse.

What specifically went wrong when you tried that?:
Clicking on a trial (staircase) loop causes the following error.

Traceback (most recent call last):
  File “/Applications/”, line 3360, in OnMouse
  File “/Applications/”, line 3315, in editLoopProperties
  File “/Applications/”, line 1230, in __init__
  File “/Applications/”, line 1732, in updateSummary
KeyError: ‘conditionsFile’

For a ‘loopType = Random’, this is not a problem.

My code worked perfectly well one day, but now it pops this error. I tried reverting to an earlier version which worked well previously, but now i am experiencing the same issue with that version, as well.

Additionally (and im unsure whether this is related), the cursor is stuck as the ‘watch icon’. Restart does nothing to resolve this.


Update: Works on windows 10, flawlessly.
