Lightning not working after upgrade

Windows 10 machine. Thunderbird upgraded to 52.4.0 yesterday and I lost Lightning when it did. I've tried reinstalling Lightning, tried downgrading TB and then reinstalling Lightning and tried disabling Lightning, thinking I could re-enable it. Nothing has worked so far. Lightning remains disabled and I can't figure out how to re-enable it. TB remains at 52.3.0. Any thoughts on how I can get Lightning back? Many thanks!

Chosen solution

Issue resolved. I decided to shut down TB and then reboot the computer (I'd done this several times previously without success, but why not?). After the reboot, I started TB again and lo and behold, Lightning is back working with everything intact. I am at a loss to explain how and why that worked, but I'm not going to look a gift horse in the mouth.

Thank you for all of your efforts today in trying to help me resolve this. I have to think that at least one of the steps you suggested contributed to the solution and I truly appreciate the assistance. Have a great rest of your day!

I've done the "Restart Now" option for Lightning several times and it seems to have no effect - still shows as disabled and still shows the option to "Restart Now".

more options

From your picture, it looks like you have the Calendar open in a tab, which might disable Lightning on restart. Close the tab, restart TB, and see if you can enable Lightning.

more options

Didn't have the calendar open, but did the restart as you asked anyway. No change. See attached screenshot. Thanks!

more options

When you reinstalled Lightning, did you first Remove it from the Add-ons Manager, restart TB, and then install it again?

more options

I've never seen a remove option in Add-ons Manager. The only thing close is the Undo option. Where would I find the remove option?

more options

I've attached a picture of my Tools/Add-ons/Extensions tab. When you click 'More' for any add-on, you should still see buttons for Options, Disable/Enable and Remove, which are absent in your picture. Which makes me think you have a damaged or incomplete TB installation. A reinstall of TB with the full installer will not affect your profile folder. Manually removing the Lightning add-on involves deleting the {e2fda1a4-762b-4020-b5ad-a41df1933103} folder in the extensions subfolder of the profile folder (Help/Troubleshooting Information, click Open Folder, close TB before editing the profile folder).

more options

Ok. Shut down TB, deleted the {e2fda1a4-762b-4020-b5ad-a41df1933103} folder, re-installed TB, restarted TB and attempted to install Lightning again - same exact results. See attached screenshot.
