What devices have you plugged into your USB hub? and is it powered? If so what is the amperage of the PSU. I can see you're booting off a 64G SD card, with multiple USB devices.
You are getting errors, usually related to power issues.

Can you try unplugging non essential USB devices and see if that improves the situation. Or if you have a spare USB powered hub try that.
