Hey thanks for mentioning this. I'm still not sure what is causing this critical error! I am reaching out to the programmer of the tool that I used to create this (Maize Sampler) to troubleshoot. I'm going to keep working on it in the meantime.
I've been trying to open the same project, and this seems to be a bit inconsistent. After trying like 15-20 times, it finally opened again, with no errors, and it seems to be working normally. This happened before tho, and then when I close the project again, and try to re-open, it breaks.
