Hey there everybody.
With an issue like this we can’t typically work on everybody’s problem at the same time because a lot of you are going to be having completely different issues. Some may be bugs, others may be conflicts with software, etc.
Before we talk troubleshooting and what to do about this, please note that there is an active bug right now where the game does not even launch succesfully on CPUs which do not have AVX support. We’re working on that, and you can read more about it at this thread.
If the game is launching successfully but crashing after, there are a bunch of things that can cause that, and we’ve been able to help players fix a lot of these crashes over the last day. If you’re crashing at any point after the client launches, try the steps here.
If this does not fix your issue, we recommend creating your own individual thread to get support from the community or contacting customer support directly.
