ArcGIS Pro 2.3 Model Crashes

In ArcGIS Pro 2.3, I have a model that--until Friday--was working just fine. It's a pretty simple model that performs some simple very simple tasks. Truly, nothing complicated at all, and again, the model was working just fine until about noon on Friday. Then, quite suddenly, it caused ArcPro to crash. I opened the project back up, went to edit the model, and now it crashes ArcPro whenever I try to do anything to it. I can get it to open up, but that is it. If I try to delete an item, add an item, cut/copy/paste an item, move an item, validate the model, literally ANYTHING... ArcPro crashes. Does anyone have any idea what might have happened, if there is a way to fix it, and how to prevent it from happening again? It seems like it got corrupted somehow, but I have no idea what to do about it (other than build it again from scratch). Note: there are a few other equally simple models in the project, and those still seem to work fine. Any ideas as to what might be going on with this one particular model? Thanks in advance!
