Glad to hear the connectivity issue has seemingly resolved itself!
As for iCUE crashing, I’m genuinely stumped as to why this may be happening. I’ll pass this information on to the team to see if we can recreate the issue. Though this may not be looked at for some time.
I’m unsure if this will help, but you could try a clean reinstallation of both Darktide and your iCUE software. I appreciate that it’s quite a length to go to though without any guarantee of it resolving the issue though:
