Workspace says that gradle is on. even when is idle . ended killing any changes in the workspace (solved)

(solved. solution in the comments and opening a bug report not)

i have found a weird and big problem that my workspace have been suffering

the problem is the next

even when i just started the workspace. it simply get *stuck* with IDLE GRADLE. i cannot open anything from the debug options

i cannot even regenerate workspace gradle/code. since the buttons. like doesn't do anything  simply. crashes 

can't be :

low computer specs. since i have even bigger workspaces and nothing ever happened

neither can't be internet.  since other workspaces that i create/open goes PERFECTLY

offline gradle just kills the workspace and i have to use a backup (that. already have the problem when i created that backup and deleted a older one)

this problem just randomly showed up. together a random weight increase in the workspace (it weights 7 GB.)

i have been tried basically amost everything.

reinstalling the snapshot

reinstalling completely mcreator with all specs

creating a new workspace and copying stuff like textures/models and the elements

The unique thing that i have not do is the pure brute force. copy all procedures and recreate manually each element that cannot be copy paste with a file

but this is where the main problem finds

i have seen that this problems comes from the .mcreator file in the workspace

it weights around 600Mb alone. is the unique file that causes this problem. 

and since is the ONE CORE . that allows my elements to be used. everything screwed up

i can open the workspace but cannot close it. since when i try 

(there are currently gradle task running in the background)

and. just crashes

console is blank. even when trying to edit something

also. if i edit something it seems to be normal. until i use the task manager (no other options)

and it deletes any progress that is not a texture edit

if have ANY plausible solution/question please say it.

(the main reason i am so desesperate is that i have some complicated procedures(not heavy. more maths and that))

if you REALLY want the workspace to see. i can find a way to upload the 7 GB and send a link
