Minecraft 1.16.5 not working!! Please help

[WillowtheRainFawn]

Please excuse my ignorance in the formatting of this and if this is the wrong place to post this,(or wrong tag, phrasing, etc.) please tell me!! First post here since I needed help and found this website ^^" I'm open for any pointers!

 

So, I tried out 1.17.1 Minecraft (not sure if that'll matter, but just in case it does) but I needed to go back to 1.16.5 (with forge) to try to salvage months of work I had done and saved via world edit. I added the 1.16.5 installation with forge back into the Minecraft launcher (because it disappeared when 1.17.1 appeared)

 

It went to the main screen perfectly fine, no issue- but when I was loading into a new world to paste the work from worldedit into, it crashed right as is reached 100% on loading?? I never had this issue prior to 1.17.1 and now I'm really lost and super stressed because, again, months of work that my VAs are excited to see ;.;

 

(please excuse any ignorance for anything blatantly obvious in the code for what's going on. ^^" my sister's the code expert, not me in the slightest! Any and all help is very appreciated)  

The crash report was this:

EDIT:

After coming back to this, I decided to install a vanilla version of 1.16.5 in the launcher, but the same thing happened when I tried to open the new minecraft world.

Here's the new crash report:

Nevermind ^^" fixed it! I just needed to replace the current worldedit with 1.7.5 version. All is fine now  (Still lost a LOT of work, including the entire blueprint I had laid out, but at least some of the more detailed work has been able to be pasted. I didn't save another finished and polished building, but you know... I saved a few good months of work so I'll take it!!
