Routines disappeared after downloading 2021.2.3

OS: Win10
PsychoPy version: 2021.2.3
Experiment link: Pavlovia
Issue: I downloaded the new PsychoPy version and now my experiment’s routines aren’t showing up in builder. In the screenshot below, you can see that there aren’t any routines in the flow and there are way fewer routines available at the top than there were before. I created the experiment in 2021.1.4. It’s bizarre because it’s only happening with this one experiment. I opened another recent experiment that I also made with 2021.1.4 and everything’s there as it should be. I thought maybe something happened with the file, so I downloaded the PsychoPy experiment from Pavlovia (that still works like I last had it) and the same thing happened with that file. Another detail that might be related: I had been working on this code in PsychoPy just fine yesterday, but then my school’s IT guy was supposed to upload 2021.2.3 last night but said he couldn’t open it. I checked today and sure enough, the entire program just wouldn’t open all of a sudden. When I clicked on the app, builder, and coder, nothing happened. So he just had to uninstall the whole program it to then install 2021.2.3. I’m not sure if that has anything to do, but I figured I’d add it just in case. So does anybody know what could be going wrong? Would anybody with 2021.2.3 be willing to download my PsychoPy file from Gitlab to see if the routines show up for you? Should I just redownload 2021.1.4? Thank you!
