MY SETUP:
Win10 Home on a virtual machine
EdgeHTML feature

THE ISSUE:
I'm running Win10 Home on a virtual machine and for whatever reason window.external.invoke always returns undefined rather than a Promise I can wait on (which I need for my javascript logic). But the invoke call is still making a rust api call that is working fine besides this one issue.

Unfortunately after searching through the issues it looks like I'm the only person experiencing this problem. But if anyone else is having this issue or has any advice to fix this please let me know.
