Problems with metadata when exchanging photos between Lightroom Classic and Photoshop.

[erwinb]

I have installed the latest versions of Lightroom Classic (12.2.1) and Photoshop ( 24.3.0) on Windows 10 (64-bit). Windows 10 is also up to date: 10.0.19045.2728.
My procedure is this: I call up Photoshop for a scan from a negative, passing the tiff file from Lightroom Classic: Ctrl-E, "Edit Original".
As I am only removing dust and scratches, by hand with the repair brush, I don't need a backup copy, in case everything goes wrong, I still have the negative itself as original.
Now when I save the file in Photoshop, the "metadata conflict" sign appears in LRC on the thumbnail in the filmstrip and I see the old version of the photo as it looked before the dust was removed.
If I then save the metadata and load it from the file again, I see the new version of the photo. So far so good, so a workaround.
Then when I edit one photo after the other, it happens that several photos get stuck when loading the data. In the filmstrip view, the mini-views have three dots at the top right and the Windows Task Manager shows me that LRC is running with a high load. When I quit LRC, it tells me that metadata is being written and I have to choose to quit anyway.

Next problem, when I send a photo to Photoshop in portrait format, it reappears in landscape format after saving, without me having touched the metadata. This was a problem before, but fixed with an update a long time ago.

However, the problem with the metadata is new. Since the last update, or the one before last, it suddenly happened that my tiff files were not opened directly in Photoshop, but in Camera Raw, without me changing anything in the settings. I was able to change this problem in the settings for Camera Raw in Photoshop. At the same time, the problem with the metadata also appeared.

Hello again!

Am I the only one with that problem?

If not, it only works when I quit LRC and start Photoshop directly. I edit my photos and after I quit Photoshop, start LRC, select all the edited photos and have the metadata written to the files as the very first step.

In order to avoid that Photoshop moves the cropping of superscripted photos (which otherwise always happens), I also had to configure that Photoshop ignores the information regarding orientation. This way, Photoshop also leaves this part untouched.

I've tried Version 12.3 and the issue is still there, nothing has changed.
