My windows 10 copy/paste clipboard is blocked, what could be the cause?

So I just noticed I cannot copy or paste anything. This also affects the clipboard history feature hidden under WinKey+V.

What is the strangest thing is I found a tip on the internet that you can use windows clip command which accepts output from previous command and saves it into clipboard. So this should place "hello" in your clipboard:

echo hello | clip

Wish I knew about this in the past.

The weird part is I get an error even when trying with a super user shell:

D:\>echo dd | clipERROR: Access is denied

Glad the error is this short as I did have to manually rewrite it here.

Any ideas what could be happening? I can just restart my PC and per previous experiences, it should fix it, but I'd love to know what is going on.

Additional context:

• PC is fully updated as per IT policy - this is a work machine
• Restarting the clipboard service alone did not fix the issue
• restarting the PC fixes the problem every time it has occurred, but this can be inconvenient at times
