Couldn't load plugin in Egde PDF

Hey!
So I was just opening a course file to study for my exams when I was suddenly faced with this page, and it's not about one single PDF; it's every single one that I try to open. And yes, I tried opening it on other apps like Firefox, and I can see the contents there, so unlike what most replies suggest, the file that I am trying to open is not corrupted.
I have tried modifying and restoring Edge through settings, and have tried clearing the cache as well. And none of it works.
And FYI, I had this update in Windows today, and after that, it started to act up. Can anyone please suggest any useful measures?

    Use the built-in troubleshooting steps for Microsoft Edge and PDF viewing, focusing on fixing Edge itself and verifying PDF support.

    1. Make sure Edge is up to date
      • In Edge, select Settings and more (… ) > Settings > About Microsoft Edge.
      • Let Edge check for and install any updates, then restart Edge and try opening a PDF again.
    2. Clear Edge cache and browsing data
      • Select Settings and more (… ) > History > Open history page.
      • Select Delete browsing data.
      • Set Time range to All time.
      • Select at least Browsing history and Cached images and files, then select Clear now.
      • Test opening a PDF again.
    3. Repair Microsoft Edge (if not already done exactly this way)
      • Close Edge completely for all user accounts on the device.
      • Go to Start > Settings > Apps > Installed apps.
      • Find Microsoft Edge, select it, then choose Modify.
      • When prompted Do you want to allow this app to make changes to your device?, select Yes.
      • Ensure the device is connected to the internet and select Repair.
      • After repair completes, open Edge and test PDFs again. Repair should not remove browser data or settings.
    4. Check if the PDFs are protected/IRM PDFs
      • If these course PDFs are protected (for example from an IRM-protected SharePoint library) and have protection applied, ensure:
        • Edge version is 83.0.478.37 or above (check under Settings > About Microsoft Edge).
        • Signed in to Edge with work or school credentials if required by the content.
      • To open a protected PDF in Edge, use Open > Open in browser.
      • If the PDF is in an older protected format that Edge cannot open, use one of the supported readers such as Microsoft Purview Information Protection viewer or Foxit Reader, as listed in the documentation.
    5. If Edge still fails only for PDFs
      • Try opening the same PDFs in another supported PDF reader (for example, Microsoft Purview Information Protection viewer or Foxit Reader) to confirm they open correctly.
      • If they open elsewhere but not in Edge, and all steps above are completed, report the issue from Edge: Settings and more (… ) > Help and feedback > Send feedback, including that the problem started after a specific Windows update.

    If the issue coincides strictly with a Windows update and persists after Edge repair, using an alternative PDF reader (such as Microsoft Purview Information Protection viewer or Foxit Reader) is a supported workaround until a subsequent Edge/Windows update resolves the plugin/preview issue.
