Solved: Weird "NetworkError" in flow reviews

Weird "NetworkError" in flow reviews

I was stress-testing the Mail throttling limits with a colleague today to simulate what would happen if multiple users submitted forms with attachments simultaneously and multiple admins approved them. Glad I did, because things went a little bonky.

How the two flows work:

st Flow: Activates when a Form is submitted with an excel attachment, translating the excel file --> JSON --> entries on SharePoint List (work tracker).
- Sends 1 email to the form requestor, advising their form was received
- Sends 1 email to Admin responsible for processing the users in that form
nd Flow: Activates when the Admin presses a button in a SharePoint List, changing that user's status in the SharePoint list to "Completed" and a bunch of other stuff on the work tracker.
- Sends 1 email to the form requestor, advising their user request form has been completed
- Sends 1 email to a string list of users welcoming them to the system

These are the errors that occurred, and searches online and the documentation have not been very informative so far, hoping I can get some help.

Flow 1 Errors:

"Unexpected error. NetworkError when attempting to fetch resource." Also, the "IF" statement says that there were no inputs?

Flow 2 errors: Two succeeded, one failed, unknown why.

Same error. All three of these were run either by myself or my colleague (who had rights to run and had no issues running these yesterday). Some emails sent, some didn't.

!!!Update while writing this post: I expanded all the other items, and they ALL display the same "NetworkError" message. See below:
