Photoshop 2023 doesn't open psd files from older version

[Paul Ed]

Hi everyone,
My photoshop 2023 is just fine with any file format except .psd files that are from previous versions of Photoshop. While opening them, it just crashes and a report window is shown. This problem doesn't occur with opening the .psd that I just created with this version. I tried every solution that can be found on the internet and none of them worked. The display driver is up-to-date, deactivating native canvas, disabling the use of graphic processor, checking older GPU mode, and some other solutions didn't work either.
My system is:
Dell xps15 9500 laptop
Windows 11
GeForce GTX 1650 Ti
DirectX 12

After uninstalling and reinstalling the program, the issue is gone and old .psd files are now open normally.

I can't wait to uninstall and reinstall after reading this. But wanted you to know that I had the same issue in the middle of a big deadline. I ended up going to PS first and " open" a file from lightroom and it was indeed the unflatten work I needed!
