I use Lightroom Classic 9.4 and Photoshop v 21.2.4 (via subscription). Just in the last few days images that I edited in Lighroom, then chose Edit In Photoshop and Saved (NOT SAVE AS), do not seem to be in Lightroom on return.
The PSD files are actually in the directory where the images are stored when using the Windows File Manager to determine if they were saved.
I have not been able to find a solution for this problem. Worked before with no difficulty.
