Photoshop 23.3.2 not working well

"4 GB of RAM, and this version of photoshop requires at least 8 GB.  Could this be the issue? "

Yes, it can! Depending on OS you may need 4GB only for itself and running processes. At the moment my Windows 11 is consuming 6,6GB of memory with Edge browser active and no other application running in parallel. Photoshop needs RAM and you need at least 8GB but that does not mean it will run smoothly and fast for all tasks. Consider 8GB upgrade, even better 16GB of RAM if you can afford and install on your motherboard.

When Photoshop crashes or freezes, this is the first thing to do, try resetting your Photoshop preferences. Press and hold Alt+Control+Shift (Windows) or Option+Command+Shift (Mac OS) immediately after launching Photoshop. You will be prompted to delete the current settings. You can also reset preferences upon a quit if Photoshop is running by going into General Preferences>General>Reset on Quit.

If that doesn't work, a few other areas to try: 

• Go to Preferences > Performance... and uncheck Multithreaded Compositing - and restart Photoshop. Better? 

If that doesn't work, Go back into Preferences > Performance... click Advanced Settings... and uncheck "GPU Compositing" - then restart Photoshop. Better?
