Ticking memory connection?

[Intrigued_Voyager]

After reinstalling my OS, I forgot that Minecraft files would not be saved and thus everything from mods to worlds got wiped. I used file recovery software to restore my brother's old save, but I can't seem to load into it as it crashes each time after spending a few moments on the loading screen. It gives me this error:

 

The game crashed whilst ticking memory connection
Error: java.lang.ArrayIndexOutOfBoundsException: -3333804

 

The full log:

Considering my tale I'm just hoping it's something fixable and not... yknow. A corrupted save. That would suck immensely.

I tried looking into the problem but I found nothing quite like it and no solutions that could solve it.

The world is corrupted.

My worst fear realized... ?

Thanks for telling me though. Is there any way to recover deleted saves without them corrupting, or is corruption a given for this situation and I should give up hope? I dont want to waste my time.
