Hi Yoon,
Can you please provide some more details? In what way does the code “abort”? Also, I assume you’re running the nightly build, not 0.12 or 0.12.1, since you couldn’t even load your experiment in those.
Have you modified the experiments in the shared Dropbox folder you referenced since running them successfully on 0.11? I ask because
1_RSVP_shapes/1_shapes.mwel, for example, looks to be controlling fixation point visibility via the alpha multiplier (one of the potential workarounds I suggested), but Dropbox claims it hasn’t been modified since 1/31/2023.
Thanks,
Chris
