USB-C Hub disconnecting occasionally

Hello! I am having an issue where my USB-C hub is disconnecting occasionally, normally one or two minutes after I plug it in whenever I want to use an external monitor and an external keyboard and mouse. with my MBA. When the issue happens, my external monitor would go black, and I would have to click with my mouse or keyboard to turn it on again. The last time it happened (today), even the mouse and keyboard stopped working along with the external monitor, so I had to unplug and plug my USB-C hub back into my MBA's port.

My power adapter is plugged in whenever I want to use an external monitor, and after restarting my laptop, the issue still persists around once a day. I am on the latest version of macOS Big Sur. I am using an Anker 5-in-1 USB-C hub.

What can I do to fix it?
