This happened to me several times too, killing my raids. Most of the time it happened while I was in my inventory or searching in a container, which basically softlocked the game as it didn't respond to any input, forcing me to ALT + F4. It also happened to me once while I was just going about, could move and do stuff that didn't required me to use the UI elements. Could be related to the airdrops, but I feel it's more likely caused by alt-tabbing to a different window.
Haven't happened to me in a while, so I don't have the files to show.
Edit: Should mention where it happened: while I was in Black pawn marked room, Searching through shelves in the Bunker, and once near the Scav land exit.
