After upgrade to TB v60.6.1, Lightning add-on displays this error when attempting to add an event to calendar, "If you can see this, React is still loading or is not working right". Window then freezes & Task Manager can't even kill it. You have to kill TB completely. After backup of profile, I've followed instruction to disable, reset, remove & reinstall lightning, same error. Uninstalled & reinstalled TB, same error. Then completely uninstalled TB & deleted all instances, including reg entries; reinstalling all. SAME ERROR!

Extremely frustrating after years of smooth performance. My calendar is my life. At wits end. Please Help. Thank You!!

Note: Lightning has never worked properly since adding, but could always add events & tasks. Never did display Lightning options window, but would default to TB options every time

I am not sure Thunderbird even uses react. Do you have issues if you use another calendar provider like Google or GMX?

Thunderbird options > calendar tab IS lightning options.
