java.lang.RuntimeException: Failed to check session lock, aborting

When MC starts a world it creates a lock, so that you can't have more than one copy of MC running at one time.

When MC closes the world it deletes the lock.

Either you have another copy of MC still running, or a copy of MC crashed without removing the lock,

OR you copied the save while MC was running and are trying to use that copy with a copy of the lock [which would be a bad copy since MC was still modifying it]

Thank you for helping me

I can assure you the game was not running when I copied the saves folder.

I can also tell you there is no other copy of MC running.

Maybe when I uploaded the file to google drive there is a trace of that lock somewhere in my computer?

I tried to reboot obviously it didn't solve the problem

Do you have any idea what is the next step? I'm completely lost myself as I am not that good with computers

i got it!

i may not be good with computer but i know how to use my good old friend google hahaha

i just deleted the lock file in my save folder and it it now working

thank you so much it is realy really really appreciated it!!!
