These are not real fixes and I don't understand why they are being repeatedly suggested by support members. The game is literally freezing and crashing which has nothing to do with startup, port forwarding, routers and firewalls.

Anyone that has worked in tech support or on computers having problems like these know that it's best to rule out all these things first. You would be shocked at how often a router or antivirus program can cause problems. I ran into the antivirus problem a few times a month in my ~10 years doing support. Most of the time it's someone running some no-name antivirus or a very outdated one.
