Studio Display keeps disconnecting usb-c devices

I have a Studio Display connected to a 14" macbook pro (M1 Pro). I'm using the supplied thunderbolt cable to connect the display. I have two devices connected to the display's usb-c ports:

• a Sandisk Extreme Pro v2 2tb SSD
• uni usb-c to 4 port usb-a hub (with attached keyboard and mouse)

Randomly, every 1-3 hours, the usb-c devices will disconnect from the computer. The display keeps working, and the speakers and webcam both continue to function, but any usb-c devices aren't recognized as being plugged into the computer. I have to unplug the thunderbolt connection to the laptop and plug it back in. Usually it recognizes devices the first time I unplug it, but sometimes it takes a few attempts.

I've had the uni hub connected directly to the laptop for awhile and have had no issues. The SSD is using the supplied cable and I used it for a year on an imac with no issues.

I am running Monterey 12.3 and updated the display firmware to 15.4. I just saw that 12.3.1 was released but it's not showing up in software update. I will try that when it's avialable. Not sure if the firmware will also update to ios 15.4.1.
