investigating Game crashes when joining cpg seat (multicrew)

[Keyser1800]

Hello,

The game has been crashing when attempting to join a multicrew session as CPG. It was working fine yesterday and I could join without any problems, suddenly the game crashed and I havent been able to join again as CPG in multicrew.

We are also getting this a lot. If the CPG joins into an aircraft that is already running, the CPG will get a CTD. If they join a cold aircraft with the PLT, then they start up, it is fine.

Can confirm. CPG joining mid-flight has a high chance of crashing the game, for the CPG at least.

Looks like it's related to synchronizing cockpit status.

I had someone hop in my front seat after I had been flying for a bit last night without a crash.  This was in a hot-start aircraft.  Are you seeing this with hot-start, cold-start, or both?

[Ignition]

Still happening.

Cold Start.

This issue has several years now and it gets really tiring.

[Ourorborus]

Still happening. Surely this could be fixed by now. Makes it really difficult to get a helicopter squadron up and running when every second crew combination fails to work.

Do you guys use OneDrive by chance, for instance to store your user profile (and with that your saved games folder)?

The error code is a OneDrive error which looks like whenever you try to join, there's an error retrieving data from onedrive.

Please supply the most recent crash files you are seeing, thanks!

We have the same issue on CPG spawn with ending in CTD, either hot start, cold start, dynamic spawn will make a different.
This Issue starts first with the last Update.

I didn´t use OneDrive on my Gaming PC, so unfortunately may not the problem core.
