Need Help Urgently

Hello
I was building my map with World Edit, I wanted to download MCEdit to see if I could use it, I couldn't use it, I pressed all the buttons and it didn't work, so I deleted it.

Except that!Now I can no longer use WE, only the //sel poly command still works.

I can no longer select an area with an axe, I can no longer do a sphere or anything else...

I also had the WorldHandler mod that I can no longer use either. On the other hand! World edit still works on other parts, I had to touch something on MCedit to make WE stop working, I panic and I'm afraid I can't use WE on a map anymore or I spent months and months of work I beg you, help me! (This may not be the right room to post this discussion, I didn't find a room that needed help)

Thank you in advance

 

Have you tried removing WE and reinstalling them?
