like I said above my game crashes if I jump to a new allocated memory region. It not even need to have anything and I can nop my code without any problems.

An example:

Code:

[ENABLE]
alloc(newmem, 1024)
aobscan(aob,F3 0F 10 86 A4 00 00 00 F3 0F 58 C1)

newmem:
//something or nothing

00D04C14:
jmp newmem      // <-- crash because of this jump
nop
nop
nop
//nop     //or just using the nops with those others and it work fine
//nop
//nop
//nop
//nop

[DISABLE]
dealloc(newmem)

00D04C14:
db F3 0F 10 86 A4 00 00 00


Well, I don't see any reason but probably it could be a kind of anticheat?
Does someone know why this happens?

newmem doesn't execute the original code, and doesn't jump back to after the original location

try the default code injection template
