64 bit memory error (SOLVED)

Three days ago I was playing with my MILSIM group doing a regular mission when out of the blue I got a error saying 'The Instruction at 0x####### referenced memory at 0x#######. The memory could not be 'read' Click on OK to terminate the program.

Ever since I cannot launch 64 bit Arma, it just crashes for me giving the same error. 32 bit works for me but causes lag whenever I pass by other vehicles ingame or whenever I am flying, any suggestions? 

Things that I've already done : 

- Validated Files

- Reinstalled Arma

- Removed Arma documents 

Try putting -malloc=jemalloc_bi   in the launch options

Fixed crashes ingame for me, only problem im still facing is that when disconnecting from a server Arma says go fuck urself and crashes my pc if not runned in windows mode

Where do I put the  -malloc=jemalloc_bi exactly?

I run in fullscreen window anyhow for the MSI gaming app.

go to library, right click on arma and select properties. then go to genereal, set launch options, and paste that in there

Might have something to do with the Nosplash etc.

That just skips the long intro, only improves loading times...
