PsychoPy Extremely Slow/Unresponsive (Both v2021.2.3 and v2024.2.4)

Other
1

Operating System: Windows 10 (freshly reinstalled)
PsychoPy Version: both 2021.2.2 and 2024.2.4

Problem:
Since yesterday, PsychoPy has been unresponsive on my device, despite previously working fine with 2021.2.3. Reinstalling Windows 10 and different PsychoPy versions didn’t fix it.

Symptoms:

  1. Extra dialog window appears on startup (never saw before).

Compatibility information

From 1.73.04 to 2024.2.4:

There were many changes in version 1.74.00 that will break compatibility with older versions. Make sure you read the changelog carefully before using this version. Do not upgrade to this version halfway through an experiment.

  1. Responsive only when:
  • Adding Routines/Loops in Builder
  • Adding Components to a Routine
  1. Slow or unresponsive for:
  • Opening local files
  • Running experiments
  • Importing media

Example:

When running an experiment:

  • Random delays (3+ minutes) before experiment starts
  • UI freezes: Moving mouse over the window turns it gray during delay
  • Random delays of up to several minutes between stimuli, even with 0.25s ISI set.

Any help is much appreciated!

Do you have a large number of routines and/or components?

Thank you for your reply. In fact, the “.psyexp” file I tried to open and run was the exact same experiment that had successfully run before. Moreover, when I recreate a new experiment with only 3 routines and 16 stimuli, I still encounter the same issue.
