When I copy and paste and move/scale the object, an error message pops up that prevents me from save

Just as the title suggests, I duplicate my object or image, and when I try to move it/enlarge it, I am unable to save it afterward. I have tried saving as a jpg, png, PSD copy, and others, but it still gives me the error message of, "Could not save “document_title.psd” because of a program error.". It is super frustrating because I am unable to progress in my painting and designs. I have searched online and some have helped, such as changing the bit channel from 8 to 16, saving, then switching back (but this only works one time per object, so it gets very annoying to change the bit channel every time I get the error message. If anyone could help, then it would be very appreciated!!! (This problem has never occurred over the past 4 years until today, and it is highly frustrating. Also recently, my photoshop has been freezing with the rainbow spinning wheel and makes me force quit. I use a Macbook Pro and it shouldn't be a storage issue because I have 100+ Gigabytes left.)
