There's a problem with the flow's trigger. Fix the trigger, Error clicking link, application doesn't display anything, won't load

[JayAnderson]

In my flow, I originally tried to initialize a variable. I didn't name it right away, and the application named it Initializevariable_Value. I have since deleted that action. Now when I try to run the flow, I get an error, it cannot initialize that value. I do not know where to correct this.

When I click on Details of the flow when in Solution view, it shows a link to Fix the Trigger. Clicking that link is unsuccessful:

You don't mention what kind of trigger it is, but based on the naming I suspect it was a Power Apps trigger and the variable name was generated by using the Ask In PowerApps entry in the dynamic content dialog.  Deleting the action where that entry was won't remove the parameter.  To remove the parameter delete and replace the trigger. That should fix the trigger error you are getting.

The trigger must have been automatically inserted. I do not know where to find the trigger.

The trigger would be the first action in the flow.  For example, in the flow below it is using a Power Apps trigger.

I had deleted the trigger from the flow, and it is no longer present. The constructor was still expecting the variable to be present, when it was already deleted. The Fix the Trigger link is probably pointing to a trigger that has been deleted. That is the only theory I have.

Deleting and re-adding the trigger will let you fix the flow.  You still need to remove and re-add the flow in Power Apps to get it to pick up the new parameter list.
