Hi Power Automate team,
I'm trying out Desktop UI Flows, using a simple flow that takes a parameter, opens notepad and types it in, then saves the file with a random filename. I'm able to get the UI Flow to work fine in test mode. When I try to invoke it from an Instant Flow, it fails with the error shown below (full error message below it). I have a 2 minute video of the process here: https://youtu.be/Fl3PMKEDEJU
Is this post-release preview jitters or something I'm doing wrong?
I'm using a default environment in region North America.
