Can't pin the launcher to taskbar (somehow fixed itself)

When I press the pin to taskbar button on the launcher, it automatically unpins itself after about a second. This glitch is really annoying since I usually open it using the taskbar. Closing and re-opening the launcher doesn't fix it either. This only happened after updating the launcher, so I don't think it's a problem with my computer.

Edit: the bug somehow fixed itself and is no longer unpinning itself
