BattlEye — BattlEye anti-cheat (PUBG, Destiny 2, many others)

When blamed in a crash: Very likely the true cause

What to do

BattlEye's kernel driver. Repair via the game that installed it.

In the game's install folder, run the BattlEye uninstaller, then verify game files in Steam/launcher — BattlEye reinstalls clean.
Update Windows fully.
If it persists, check BattlEye's FAQ for known conflicts (old antivirus and RGB utilities feature often).
