Just tried to enter a MP-Session with the server named TRT-World.eu. The Track was Spa. It enters the loading-screen for the MP session but was interupted with a Crash-Dump. So I wasn't able to join that session. I tried a few other MP-Servers and Single-Player - that worked without a problem. 32bit or 64bit was the same behavior... here the Dump-Files
Also here on some players. Sometimes and then multiple times Crash while joining an server. Not an specific server.
Had it again on another server after I had three MP-Races... so looks a bit random. There are always users active on that server while I try to join. Maybe it's because it was in quali already? Not sure but in this and if I remember right the session were I first get that Dump was in Quali, too.
I'm having this issue on any server that I try to join when selecting the new Audi. It's happened over 10 times?!
have you tried it with a different car? I had that dumps with the Callaway Vette and the AMG GT3 - so seems not to be related to a car on my side...
I have also experienced this issue, for Rennsimulaten.de 4 on Spa. This was selecting the Z4. 64-bit version only, might test other variables soon.
After some more testing it was happening with any car. I seem to have solved it by deleting my controller profile as once I did that it never crashed again.
