What "solutions" did you use?
How many of these files did you "get back"?
Just a few?
Or... a lot of them?
If "user-level" data recovery software can't get back the data you want, you could try a professional data recovery firm, but be forewarned: they are VERY expensive. We're talking about the possibility of thousands of dollars.
Hmmm....
You said the files were on an SSD?
That changes things, in a very bad way.
Retrieving deleted data from an SSD is much less likely than doing so from a platter-based hard drive.
My guess is that what you've "gotten back" now, is "all you're going to get".
You may just have to write this off, and start over.
In the future, I'd suggest running an "immediate backup" on your project SSD whenever you finish a session.
