Very recently began experiencing the above 0xC0000005 STATUS ACCESS VIOLATION error within a few minutes of playing in multiplayer rounds. Sometimes this error prompts as soon as I join the match, and other times it happens anywhere from 5-10 minutes after joining.
Steps taken:
-Verify files
-Reinstall Windows
-Reinstall Arma 3 on SSD
-Reinstall Arma 3 on HDD
-Run 32 bit launcher
-Run dedicated new & old profile parameter
-Disable OneDrive (perhaps OneDrive is locking profile items stored in My Documents or other default OneDrive directories)
-Delete Arma3 folder in My Documents
-Delete Arma3 folder in Appdata > Local
-Delete old profiles, then recreate new profile in Arma3
