"Invalid file name" error when no file is uploaded in SharePoint list

Question

We have a SharePoint list with some PowerAutomate flows. Everything was working fine until we renamed the list, updated some columns and used a powershell script to change the URL to match.

That said, I do not get an error like my colleagues do when they try to save a new list item without an attachment. Their error is:

Given I cannot replicate the issue and I've tried with and without an attachment, I'm hoping the community can help me unpick this please.

We are using Edge and SPO. We have the same permission levels. They have cleared their cache as I saw that one another post that might help.

In this case, it was that we had used the script to change the URL but the team were still using the old "form link" (the one from the "new" button "copy link"). #UserError
