Software flashback

Turn on rainbow six, and the software will drop

From what you say, when you open Rainbow six, the TS3 client crashes.
Uhm, could you provide some information about the issue?
Which rainbow six? (Siege, Vegas, Vegas 2, 3Gold, Lockdown)
And what do you have on your computer (Os, Graphics Card etc.)

Also an error log would be nice to provide.

Since the 3.5 version has been updated, only playing rainbow 6 will flash back. I’m used to it now. Maybe it’s Chinese. We have several problems like this
It may be the reason for the Chinese documents
