Error: CreateTextLayout failed: 80070057

Hello. I had a customer contact me saying she received the following error in one section of my app. Error occurred on a Windows machine. Desktop app built with Xojo 2018 r3

I found the following post, but the error message in the post is slightly different from the one she saw, and I’m not sure what was done to correct the issue

Any thoughts?

see CreateTextLayout

Maybe too many graphics objects?
