Game crashing after starting a new lap - My Team

Bit of a weird one. This bug has happened 4 times, 3 times at Bahrain and once at Jeddah. Exactly 0.966 seconds after starting a lap my game lags out for about 20 seconds and then crashes. This is on My Team. The integrity of my game files are perfectly fine, I wasn't running any modifications, and I'm running the latest patch on PC with no known issues. All times this has happened has been in FP1.
