USB mouse not working on MacBook after plugging it in a PC

I have a plug and play USB mouse which worked perfectly fine on my MacBook Pro 2020 (using a dongle to add USBs), until yesterday when I plugged the same mouse in a PC laptop. Now the mouse won't light up or be recognized by the MacBook. I tried rebooting, unplugging, all three USB ports in the dongle, switching the dongle to another USB-C port. I think the dongle should be fine as I can still charge my Mac through it.

MacBook Pro 13″, macOS 10.15
