Is the image a high-precision one?
Typical image file is from a film scanner, medium format color negative, 4,800 PPI, 97,955,104 pixels.
Gimp Preferences/Folders/Other says the swap file is in folder C:\Users\RJD\AppData\Local\Microsoft\Windows\Temporary Internet Files\gimp\, which doesn't exist.
I understand neither why Gimp points to that folder, nor what is in ...\Temporary Internet Files\.
Tile cache size is 8,330,310 Kibibytes.
My plan: Keep Dashboard visible. Save XCF often. Maybe enlarge tile cache to 12 GB.
Here is a typical Dashboard:
Cache
Occupied 6.8 GiB
Limit 7.9 GiB
Swap
Occupied 163.8 MiB This seems odd, since available memory is 4.8 GB.
Size 164.0 MiB
Limit 216.0 GiB
Memory
Cache 6.8 GiB
Tile 7.3 GiB
Used 8.0 GiB
Available 4.8 GiB
Size 15.9 GiB
97,955,104 pixels = 97 megapixels, for comparison a 1920x1080 = 2 mega, and you said also a 560 MB TIF file, the size is more than half GB... no need to search anymore where the problem comes from, this is a huge image,
My suggestion, if you are working with 100 megapixels/half a Giga images ➤ add RAM to your computer to get like twice what you have now, maybe even more for comfort
Your CPU might be old as well, GIMP uses CPU, what CPU is yours?
I can see how a simple rotation or a use of a brush will slow everything down, I have 24Gb RAM, few time I did manipulate images similar size, I did get a lot of time between filters to make a coffee and drink it before something happened.... and I don't even speak to add multiple layers... or making selections, especially with the fuzzy select or by color, you go straight to the wall..
A simple tip while upgrading your hardware, immediately after any use of any transform tool to limit "the damages", is to do a Layer ➤ Layer To Image Size
EDIT: I just saw "Windows 7 64 bit" your computer is 15+ years old?
