Hi Guys,
I have this flow which worked for months now and even made duplicates of the flow for different use cases,
Recently users have been informing me of an error they receive when triggering the flow. The error just said that it didn't work, and they need to refresh the page but even after refreshing the error keeps showing up.

Since it only affects a small portion of the users, I didn't make any changes and it seems like the next day they are able to run the flow. And searching for the root cause didn't lead me anywhere, since the problem is also not stated in the error. Does anyone have any clue on why this is happening?
I'm using a "For a selected item" in SharePoint list trigger.
Thanks a lot!
