"Invalid Project" or crash on load.

I made a project on the most recent version of Sampler last night, and this morning it says the project is invalid.  Or it hard crashes on loading it.

In addition files I made in 2021 won't open with a variety of different errors, either 'filters aren't supported on my hardware' or 'the file could not be read'

My experience with saving and loading in this software has been awful, I don't know what I could be doing wrong.  I don't have problems with any other substance programs, and my hardware is high end, and I have the latest version of all drivers.

Here are dropbox links for all the problematic files, I would appreciate any assistance.  I am trying to teach a class to use this software, but if it's this unreliable in simply saving and opening files, I just can't rely on it.
