Using pen tool after updating to Photoshop 26.6

After I have updated Photoshop to v. 26.6, the issue is that when I have two documents open, normal bitmap pictures, and I use the pen tool on one of them, suddenly it jumps to the other picture! I have found out, that working on the first opened picture are okay, but working on the second opened picture, the pen tool jumps to number one, and back, and loosing the path.

I'm on Windows 10, and with GPU driver updated.

I can also see that shifting between documents with ctrl+tabulator, are not working normal anymore.

I was very eager to try the new features in 26.6 (I'm not a BETA man), so I upgraded at once it came, but

I must say that I have regretted!

And by the way..... I know that this is a user forum, so does anyone know how to report such a bug to Adobe himself........ I have spend a lot of time to find the way to do so, but out of luck!
