This happened to me too. I also do 100% races, so the rule for me now is to always manually save at the beginning of last lap, because being stuck at loading screen keeps happening at random, at least once every season. And yes, you can't sim once the session has been started.
Hi guys - I have a problem with the new Striker helmet from Podium Pass 2. Even though I select it, this selection is not saved by the game and it defaults to another helmet as soon as I exit customization menu. Disregard this, another thread already exists
