What happened?

Many of the diagnostics show an error saying: "Required TraceElements gatherer encountered an error: Attempted to get a SyntheticEventsManager without initializing".

I don't know what this error message means, but I assume it has to do with some internals of lighthouse. If not, I would love to know what is being loaded on my site that is blocking this or causing this error.

What did you expect?

I expected to get diagnostic insights and not internal errors.

What have you tried?

I've tried to disable other RUM tools from being loaded just in case they were interfering with Lighthouse.
