Lost the brushes last night, present only in preset format (.psp) and won't import.

I was working last night on and Photoshop suddenly crashed. Had around 400 brushes created by me and now are available only in .psp format which I can't import, which is located in (C:\Users\username\AppData\Roaming\Adobe\Adobe Photoshop 2020\Adobe Photoshop 2020 Settings), and when I am trying to access the preset manager, there are only contours and tools to import, but no brushes. Another thing I tried was opening the .psp file directly and it doesn't open it and pops an error that states "Could not complete the request because it is not the right kind of document.". Total b*.

Hope anyone can help me with this stuff 😞
