I/O Hub Error with no eye tracking

Hi everyone,

I am having trouble running my experiment on the update (PsychoPy 2022.1.1 I believe).

I have a macOS and my programs were working perfectly before I updated, so I went back to the previous update (2022.1.0). When I try to run the program, I receive an error that I/O Hub failed to start, but I have no eyetracking in my experiment. It works on other computers and none of the program has changed.

Let me know if anyone has any suggestions! Thanks!
If this template helps then use it. If not then just delete and start from scratch.

Here is the error message that I receive.

RuntimeError: Error starting ioHub server: ioHub startup failed.
################ Experiment ended with exit code 1 [pid:35378] #################

I just ran into the same error. I noticed that in Experiment Settings > Input, the Keyboard Backend was set to ioHub. Changing this to PsychToolbox seemed to fix this issue for me. (This happened when I was creating brand new experiment, so I don’t know how changing this will affect your existing experiment)

Thank you @duncan! That seemed to fix the issue. Much appreciated!
