For me game crashes always at the same point when it just want to pass control to user (when countdown 1 wants to disappear). It could happen at first race, qualification, or many races down the line.
RTX 3080 and G923 used. Steam version.
Sometimes it just hiccup on passing said control. Hope you could fix it as I'm loving GRID 2019 so far as it has best Trueforce support among all games so far.
