Can’t delete folder in sidebar. No unpin option

There’s a folder in my sidebar. That folder is named after external drive that I have:
png1

I don’t know what I did for that folder to appear and now it’s really annoying. I think it’s a corrupted folder of my external drive which is One Touch (D). When I right click it, it doesn’t have the unpin option. Only shows this:
png2

When I tried to expand it, it showed nothing. When I clicked properties of that folder, it showed nothing like this:
png3

It has no directory so I can’t delete it from cmd.

One Touch (D) folder (yellow manilla folder not the external drive) is above This PC but still in This PC section:
png4

Anyone have solutions for this? I’d appreciate all the help I can get. Please help me delete that folder.
