What are you trying to achieve?: run a simple experiment with eyetracker gazepoint and saving the hdf5 file

Dear all,

I’m trying to run a simple experiment using Builder with the Gazepoint eye tracker.

I’m using PsychoPy version 2022.2.5 on Windows 11, always with the Gazepoint control software running.

I successfully completed the calibration and validation routines and tested with a 5-second fixation cross to ensure eye-tracking data is saved correctly. The “save HDF5 file” option is checked.

The experiment runs smoothly, but the HDF5 file is not created. Here is the error message I receive:

Error during ioDataStore creation....

Note: This issue only occurs on Windows 11. When I tried it on Windows 10, it saved the HDF5 file without any issues.

Has anyone encountered this problem or found a solution?

Thank you for your help!
