Adapt Learning Community: Error An error occurred while getting schemas

So I've done something very silly and messed up whilst playing around with an extension. I think I've created (in error) a duplicate and am getting in the console:

Error: Already found extension config attribute with key […] and then a load of node modules locations. And a lib/content manager reference.

I know I should never have done this (and will learn) but the upshot is that I can't get into the Authoring Tool, getting the response 'An error occurred while getting schemas'

Is there anything I can do short of restoring to a backup (it's on Azure/Ubuntu)? Can I replace the node modules somehow?

I *was* having a good day, too…

Any help greatly appreciated,

Jonathan

Yes, there may be some things you can try. But let's begin with just a couple of details of your situation.

version of authoring tool?
have you indeed duplicated the extension? (check for duplicate entries in Plugin Management; a screenshot may be helpful in order to know what to call each "version")
is the plug-in in question an Adapt core plugin? which one?

Hi, thanks for offering to help!

It's

Authoring tool 0.10.0.

Framework 2.4.0.

Here's the console:

error [17 Sep 19 14:06:44 +00:00] Already found extension config attribute with key _launchNewWindow (adapt-launchNewWindow-de)
