Photoshop 'freezing'

The fact that it appears, from what you have said, that Photoshop actually freezes then I suspect, if that is the case, your PC may not have enough space to do what you have asked. Recent developments in all the Adobe software are pretty hungry for very fast processing speeds, large ram and an SSD. If you are combining two images that are themselves fairly large then it may be that your computer can't cope with the speed and size that PS CC demands. You could try using PS to downsize your image so that the material it is working with will be less hungry. If this then works the answer would be to upgrade your system. Or make your images smaller before you start working on them in PS. You can check on line what the recommendations are for a good work flow from PS CC - which to replace your system is likely to be expensive, or you can try resizing the images to a smaller size before you start. But I am sure that others have found their way round this without having to spend the earth. I must say that before I upgraded my laptop last time I went for a large Ram - 32GB, and the highest spec I could afford at the time as I could see that PS was getting hungrier and hungrier.

Click on 'Task Manager' from the drop down and a window will open upon which there will be a list of whatever processes are active on your machine and a figure, telling you, by percentage, how hard your processor, GPU etc. is working and how much RAM is in use.
Assuming that nothing's running constantly at 100% and/or your RAMS all used up, the chances are that your machine's not running out of resources.

Well done for upgrading your machine - PS certainly needs some large muscles to work with. I have an add-on external Drive (plugs in to the computer with a USB cable) on which I save all my photos, leaving the SSD drive as empty as possible for the computer to do whatever is necessary. External hard drives are fairly inexpensive - of course they can be expensive if you buy one with masses of storage space but it is very easy to add to if a smaller one becomes full. To open Task Manager press Ctrl + Alt + Del at the same time. If the Task Manager can open, highlight the program that is not responding and choose End Task, which should unfreeze the computer. But that won't tell you why it keeps freezing, although it is a quicker and easier way to unfreeze it. What is the size of your photographs? And what format are you using when you try blending two images together i.e. Jpg, Tif, PSD? If you are using a format that PS doesn't recognise then that could cause it to stop working. It could also cause you very large files which are using up the 32GB ram that you have. There will be some cause it is just a case of tracking it down -Task Manager will show you if anything is using loads of speace but the fact that it is happening a lot and it is when you are blending two images is a suggestion to me that something is too big. Every layer you add will add more to the size of the unmerged/unflattened image. And that can only be a finite number before they need to be merged or partially merged.

Photoshop won't open a file type it doesn't recognise.

I may be wrong but I really don't think your problem lies with a lack of resources.

Quote:According to the Adobe website the only version of photoshop that is compatible with Window 11 is "Creative Cloud 2022"
Presumably, that means Photoshop V.22?
Which gives me an idea!
Photoshop's currently on V23.2.2, so it should be possible to roll it back to V.22.
If doing so causes Damian's problem to go away, then it would seem that there's an issue with the latest version which was introduced at the last erm, update.
And before everyone jumps in and says that that can't happen; I solved a problem that I had with a particular version (it never went away) by reverting to the previous one.
