Hi there, I've previously posted about this issue many months back and after a bunch of updates, nothing has changed.
If I am in the area of another player(s) where there is also traffic around, then go into the photo/ replay mode, the majority of the traffic disappears (it varies on how much, normally most is gone). The fact I make car chase/ race videos of The Crew 2 makes the videos/ game world rather dull/ empty. However, if I hit the vehicles in the traffic, they then appear in the replay (but only at moment of impact, otherwise they stay invisible). I think this started happening last year at some point as the traffic used to be fine when I look back at my older videos.

You'll notice on the second video the cars disappear as soon as the transition to the photo/ replay mode occurs

Troubleshooting I've tried: Verifying game files and reinstalling the game. Changing the settings to default in the photo/ replay mode.

The 2 videos below show the issue, the first linked one is new footage, the second is old footage I posted the first time.
