You were right in thinking the windows update DID NOT matter (I had looked up a similar error message elsewhere where the update seemed to the culprit, but not so here).

I was able to create the new app and recreate the old app. So really, all is good. But...
If possible, I would like to use my git repository on both machines.
What I'm going to try is copying over the new engine and config folder to the old repository and seeing if it will work.
If that doesn't work...no real worries...
let me know if you think any other folders would be the culprits, but otherwise I'll just upload the new version to a new repository.
In any case, I'll consider this case closed -- do I close it or does the site admin?

Thanks so much!

You close it by selecting the correct answer, the star

Duh! Thanks, Dan!

I get a javascript error creating a new app with Trongate app on Mac Sonoma. And the app will not finish.
Here's the (long) error:

Hi anunes, please create a new thread... Just a heads up - Macs are very picky with permissions. What I'm seeing in that error dump is your MySQL install hasn't permitted the Desktop app to use whatever user (root, etc...) you set when creating the Trongate app.
