so I worked on a big file for a couple of days, it's a collage, I drag and dropped alot of stuff, worked with photoshop for years, and I set my canvas and pixel size all to my final print size, but now after exporting, everything is squished. the mistake was: I WAS WORKING IN A 1,33 PIXEL ASPECT RATIO ALL THE TIME.
So now my result is completely wrong.
There must be a fix without having to redo the entire thing. I just can't figure it out and I have not found a solution online

The only thing I would think of would be to transform (not resize) either a f;lattened version of your file or try to transform all the layers (select them all and make sure all masks are linked), and reduce the overall width by 0.33.
Do that with the transform "tool" (CTRL+T, or edit>transform>free transform)
To be honest I never worked on those pixel ratios (It's for video so it's really a niche stuff), and you'll probably need to check the exact amount you need.
As far as I know there isn't any other way to revert back to a square pixel ratio.
