Loading into something with a high load, such as combat or having a high ammount of units in an area, causes it to do these things. It seems to not happen for other people.

Additional system info incase is nessisarry, note I am using a laptop:
NVIDIA 1050TI
Intel Core(TM) i7-8750H (2.20 GHz, 6 core.)
2667 MHz single channel ram
MX500 2tb (drive arma is installed to)

Current attempts to fix issue:
Change memory allocator to system
Ensure Arma files are not "read only"
Reinstall Arma
Reinstall Mods
Use 32bit version
Use performance build (helped slightly, but in the end results in the same issues.)
