Minecraft has a nasty tendency to keep using more and more memory the bigger your world is, even though chunks are unloaded it accesses every chunk every cca 2 minutes to save the game, which with huge worlds can be debilitating for your hardware. I also think large structures increase demands on their own. So it is possible that you exceeded the amount of memory your computer can handle and so the World Edit can't function properly. You can also allocate more ram to minecraft (although I wouldn't recommend more than half your total ram) This sometimes helps.

To do so:

1. Open the minecraft installer

2 Click on Installations (at the top)

3. If you hover your mouse over the profile you want to use, at the right it shows 3 dots, with the option to Edit if you hover over that. Click on it.

4. Click more options

5. In the JVM arguements, there is a line at the beginning that says "-Xmx2G" (for example). Change the number for a higher one to allocate that many gigs of ram.
