After restarting MacBook Pro Thunderbolt Ports stopped working I hve a macbook pro 2018 (A1990). Whenever I restart my macbook, my thunderbolt ports don't work for a while; like 15-20 mins. And then suddenly, they start working absolutely fine. I have plugged in different types of devices to make sure it's not the devices' fault (e.g: type-c hub, usb with a type-c head, A type-c to type-c cable to connect my phone). Every device is definitely receiving power from the port but os not working; e.g: the USB heats up or the phone is charging when i plug it in but nothing more than that. After a while, when the ports work normally, everything is fine, I can use my external hard-disk, transfer data to my phone, connect my M&K etc. If I just close the lid i.e: put it to sleep, instead of shutting down; everything keeps working fine when I reopen it. I have tried to reset SMC and PRAM but I don't think I succeeded in doing so because there is no indication as such. [Re-Titled by Moderator]

If restarting does not sort your issue...
