If you are experiencing issues with Excel Labs, which appears to be related to the Excel Add-in "Analysis for Excel" (AFE), and you are suddenly seeing a blank panel instead of the code or modules menu, there are several potential causes and steps you can try to troubleshoot the issue:

1. Check for Updates:

• Ensure that both Excel and the Analysis for Excel add-in are up-to-date. Sometimes, issues can be resolved by updating to the latest versions.

2. Restart Excel:

• Close Excel completely and restart it. This can often resolve temporary glitches.

3. Check Add-ins:

• Verify that the Analysis for Excel add-in is still enabled. Go to "File" > "Options" > "Add-ins." In the Manage box, click "COM Add-ins" and check if Analysis for Excel is listed and enabled.

4. Reinstall Analysis for Excel:

• If the issue persists, try uninstalling and reinstalling the Analysis for Excel add-in. You can do this through the "Add-ins" section in Excel Options.

5. Check for Conflicts:

• Other Excel add-ins or third-party software might conflict with Analysis for Excel. Temporarily disable other add-ins to see if the issue persists.

6. Repair Microsoft Office:

• Perform a repair of Microsoft Office. Go to "Control Panel" > "Programs" > "Programs and Features," select Microsoft Office, and choose "Change." Then, select "Repair."

7. Check Security Settings:

• Verify that your security settings or group policies are not blocking the functionality of the Analysis for Excel add-in.

8. Check Excel Trust Center:

• Ensure that the location where the Analysis for Excel add-in files are stored is added to the Trusted Locations in Excel Trust Center. Go to "File" > "Options" > "Trust Center" > "Trust Center Settings" > "Trusted Locations."

9. Check for Recent Updates:

- If the issue coincided with a recent update to Analysis for Excel, check the vendor's website or support resources for any known issues or updates.

10. Event Viewer (Advanced):

- For more advanced troubleshooting, check the Windows Event Viewer for any error messages or events related to Excel or the Analysis for Excel add-in.

If the problem persists after trying these steps, and especially if it's impacting your productivity or workflow, reaching out the support resources for Analysis for Excel might be the next best step.

Excel Labs is an Office add-in so those steps mentioning COM add-ins and repairing office are not necessary.

I recommend removing Excel Labs through this menu then re-install it:

Additionally, look for any update buttons once you open Excel Labs. Another thing worth investigating is if you have any pending updates through File | Account | Update Options - Check for Updates.  I've seen AFE 'blank out' on an outdated version of M365.

My guess that's due to recent issues with WebKit. Try to sign-out, sign-in and re-install add-in.

Thanks for everyone for the help. It ended up being caused by my internal IT. They fixed it without telling me what was the cause.
Generally security related.

Thank you for your very detailed response.  Ultimately it was an internal IT issue that caused it that need to be back out.

Clearing the Office Add-in cache worked for me.
