Is there any way I can get these 3 models back?

[velvet plinth]

I created 3 models in the file format .bbmodel, they were exported (apparently) as .java models. When I try to open them using blockbench they open up and there's absolutely nothing there. I know they existed because I have video proof of their existence. I had them on the 1.16.5/1.17 mappings and I updated my mcreator to 1.20 after a long while and noticed the models were broken. Is there any way to recover this?

Let me guess, you successfully ignored this small warning that Blockbench gives you?

It's been over a year since I did this.
