Could the crashing when you use the trainer be related to the additional telemetry they supposedly implemented with patch 1.02?
It will be both. They fixed some crash-causes last week with a small Patch.
But Guerilla already stated, they haven't fixed all the crash-bugs yet.
They announced another fix-patch for this week.
I myself get some crashes here and there, so... Let's hope they fix the Rest.
It's important, you do the quick-sending for the crash-reports. They are working with the Informations they got with that function.
The opposite is the case.
I contacted Guerilla befor I started using the Trainer and asked about the fact, that a Trainer could be used to reproduce the crashes.
I asked, if it is "allowed" in some kind.
They stated, that everyone is free to use 3rd party-Programms on theyr own risk and yes, it could help if you use the Trainer to reproduce crashes.
Also, If the crash-report sends them informations about using a trainer depends on, which kind of report you choose. If you have chosen the FULL REPORT, there CAN be some informations what the trainer did and that some kind of 3rd party-programm involved. but no futher informations.
If you took the "normal" report-version, there will only be the crash-cause without any further infos.
BUT: they wont restore any save files if the save or the game is breaking because of the use of a trainer.
And they gave me the hint, that most crashes ar Memory-Errors and that they are still looking into the reports. They plan to release another fix this week.
