Error deauthorizing all Apple Music devices on Windows PC

I am trying to "deauthorize" all 5 of my devices that have my Apple music on them (since I only have 1 of the 5 devices left...the others are old and recycled). I am doing this on my Windows PC laptop. I get to the screen where I have the option to "deauthorize all 5 devices". However, every time I click on it, I get an error message. I am unable to copy and paste the error message, but I took a photo with my phone (actually 2 since it was a long message) (attached hereto). In a nutshell, the error message says "Your request produced an error". Of course it doesn't even say what the error is. Can anyone help me. All I'm trying to do is get my Apple music on my new Windows laptop. It really shouldn't be this difficult!
