Hi @David LaFrenz ,
I suggest you refer to this support article:
https://support.microsoft.com/en-us/office/create-a-custom-connector-48f47591-b9d5-4e6f-9203-5b34ce09a5e9
Did you use the same PC with the custom connector?
If not, did the different PCs use the same Windows system and Office product?
Did you install any updates recently?
I also suggest you check if you can get any information from this article:
