"USB-C adaptors constantly ejecting while transferring files: I have 2 USB-C Hubs/adaptors.... while I transfer files via them, they are constantly ejecting before the transfer is complete. No matter which side they are plugged into. I have a 2019 macbook pro. The drives get super hot whole transferring."

If Ports Aren't Working:
[Hold Down: shift key, upon boot], In Safe Mode, Login Items do not run at login, certain preferences are set aside, and damaged system files are then reset. So, once booted in to Safe Mode, wait for 30 seconds, and then boot up normally, attempting another connection.
What happens when you create a new administrator user, and log int it? Do you still get this error? If not, then it is likely an error with the current user. If so, then it is likely an error with your macOS.
Sometimes when changes are made to the system(i.e. Updates), system configurations (i.e. for Ports) become manipulated, technically. So, reset the SMC and NVRAM. Try performing each thrice. It may take sometime, being certain you have the time to perform these resets.
