Hi @EP Insight,
Since you've already tried clearing the browser cache/cookies, restarting the browser and device, disabling extensions, and you've confirmed the issue occurs across multiple browsers, I'd suggest a few additional checks:
- Open the site in an InPrivate/Incognito window and see if the Site Contents page loads there.
- Try accessing the affected SharePoint site from a different network (for example, a mobile hotspot) to rule out any network-related interference.
- Ask another site owner or member to test the Site Contents page and confirm whether they experience the same behavior.
- When the page goes blank, press F12 and check the Console tab for any errors that appear during page load.
- Try navigating directly to the Site Contents page URL:
https://<tenant>.sharepoint.com/sites/<SiteName>/_layouts/15/viewlsts.aspxand see if the behavior is the same.
If the issue is affecting multiple users or continues to occur intermittently after the above checks, I'd recommend contacting your Microsoft 365 administrator and having them open a support case with Microsoft. The support team can review backend diagnostics and tenant logs that aren't available from the client side and help determine whether there's a service-side issue with the site.
- Find your Microsoft 365 admin: If you don't know who the global admin is in your organization, you can find guidance here: How can I find my Microsoft 365 admin? - Microsoft Support
- Submit a service request: The Global Administrator should create a support request with Microsoft to receive advanced technical assistance. For detailed instructions, see: Get support - Microsoft 365 admin | Microsoft Learn
If your subscription is from a partner or reseller, contact the reseller's support provider to help open a service request on behalf of you instead.
