Techne Crashes At Startup

I was trying to make a model and Techne was working properly until 3/7/2021 where it started to crash on startup after I closed it.

Heres what the report looks like:

Heres what I tried:

1. Updated my computer (didn't work)

2 .Delete all backups (didn't work)

3. Reinstall Techne (site won't load)

4. Find a new modeler (i tried to use blockbench but it didn't load in the model when i imported the java into mcreator. Yes I am on 1.7.9)
