4k video download was working great but now seems to crash often. Is there a known issue that may be causing this? I'm using a 2015 macbook with the latest macos.

I've tried rebooting, limiting threads and bandwidth but still randomly crashes. I can forward a crash report if it's helpful. I just paid $20 for your product suite because i hoped it would prove useful, but if it can't run stable it isn't useful to me. Please assist, thank you.
