What's Wrong?
Upon opening Claude Desktop on Mac (latest versions of both) Claude crashes immediately and is frozen (spinning beach ball). I followed instruction on Claude.ai and deleted cash. It told me to come here, submit a ticket and give you the logs but the .ips log files aren't supported.
What Should Happen?
It should open and work. It was working. I had Claude Code running in the API and went to bed and when I woke up the computer was very hot and the beachball was going and everything was stalled. Now if I am open it, it crashes immediately
