Cedrus RB-540 Builder Crashes

Builder

Hello,

Hoping for a bit of insight on crashes we’re experiencing while running very basic Builder files using a Cedrus RB-540 response pad. We’ve utilized the same RB-540 for similar experiment files in the past, so we’re unsure if this is a version bug or central to our setup. Details below.

OS Windows 10 64-bit
Processor Intel Core i7
PsychoPy version 2023.2.2

We’ve ensured that the RB-540 has the correct Windows drivers installed and that the Cedrus support package has been installed through the PsychoPy builder.

To troubleshoot, we’ve created a simple Builder file that only has the Cedrus buttonBox module, duration 10 seconds, so that we can confirm the RB-540 is communicating with PsychoPy. Following completion, we do see our keypresses in the data output file, but we do also receive this error message…

Curiously,
When we save, close, and reopen our Builder files, the Cedrus icon will sometimes be replaced with a generic puzzle piece. In our larger Builder files, our trials seem to crash at button press on the RB-540.
