I manage a ton of consumer Windows devices and have seldom seen this message. It also hasn’t ever appeared on any of the multitude my own Windows devices that I’m using for hours every week.
I have also seen this message with regard to other file associations like .PDF, certain image formats, and archive formats.
Microsoft has plenty of dark patterns to try and loop users back into Microsoft Edge, but I don’t think this is one of them.
Edge just happens to be the “constant” in an ocean of variables because it ships with the OS and is integrated into so many other facets.
The broken .PDF association also defaults back Edge, Image formats to Photos, Archive formats to the Explorer archive utility. I’m sure .txt would scale back to Notepad.

Likely that the browser they were pointed at went missing (executable moved or something), or was crashing at launch, and this is just Windows saying “I can’t find the default you wanted so I am falling back to Edge, otherwise a lot of stuff is going to be broken”.
