PSB error

[agnesk51843196]

My Photoshop CC 2019 has saved a psb file 2,366,301 KB and did not display error. However when I try to open, photoshop says "Could not open , because the file is not a valid Photoshop document". Anyone else had this issue? Is there a way to recover the file? Thanks

Try renaming the file name and extension, and see if you get any result,

one more thing to try is placing the file into another photoshop document or inside illustrator .

Thanks Mohammad. Unfortunately renaming did not help. I do not have Illustrator, but tried it with PS CC2018, does not open.

PS behaved weird during perspective warp, but it seemed to be ok after I undid and redid the perspective warp steps. After saving the psb I also saved a 1080 px jpg, which is saved correct and opens.
