Apex Legends Bug Kills Executing Players

An anti-climactic (but, frankly, kind of hilarious) bug in Apex Legends is instantly killing players who attempt to finish off downed opponents with executions.
As a multiplayer game with around 100 players in each match, Apex Legends is fated to its share of bugs the same way any game of its scope must be. This latest bug is particularly unusual, but not outside the bounds of what's expected in a game this big.
Reddit user u/Real_SovietUnion posted a clip of the bug in action on the game's subreddit Friday. The footage shows Real_SovietUnion getting knocked down by an opponent while riding the train around World's Edge. When the opponent tries to perform a finisher on them, the camera glitches out, showing random scenes around the map before whipping back to the finisher in progress only for the finishing player to vanish in the middle of the animation.
Stunned and confused, Real_SovietUnion hardly has a chance to comprehend what happened when the now-disappeared player's teammate approaches and starts up another execution. The same bizarre camera effect happens again, and again the player disappears mid-animation. Saved from death, Real_SovietUnion crawls away from where they nearly died and sees the death boxes of both players lying there.
It seems plausible attempting the execution while riding the train caused the bug, but it's hard to know for sure from the outside.
