"Your Windows License Will Expire Soon" message keeps popping up

Hi! So I've been getting this pop-up from Windows for the last couple days and it's honestly driving me insane - I've tried a multitude of fixes I've found online but nothing seems to work. Looking at my Activation Settings, it says the following:

Edition: Windows 10 Pro

Activation: Windows is activated using your organization's activation service

I've tried going to "Change Product Key" and inputing my product key I found using the ProduKey App but it says: "To activate with this product key, this device will have to connect to your organization's activation service.", It then loads for a bit and gives me the error message "We can't activate Windows on this device as we can't connect to your organization's activation server. Make sure you're connected to your organization's network and try again. If you continue having problems with activation, contact your organization's support person. (0xc004f074).

I've also tried using a generic activation key but once I input it, it tells me "We can't reach a critical Windows service. Make sure you're connected to the internet, wait a few minutes, and try activating again. (0x80070422). " Problem is, I'm connected to the internet so I'm not sure what's up with that.

The edition of Windows 10 I'm using was downloaded by and from a store where I purchased an SSD a few months ago, I'm assuming it's got something to do with that but I'm honestly not sure how to fix it.

Edit: I should add disabling the Windows License Manager Service on services.msc seemed to temporarily help (At least yesterday) but I turned my PC back on today and while it's still disabled, the notification continues to show up at the same frequency.
