It looks like your issue is that the path being used is your local folder (synched with SharePoint perhaps). Other users will not have access to that path.
They can set it to their own synched folder path.
But I'd recommend connecting to cloud Sharepoint folder (assuming SharePoint online).
Use Query from Web in PQ to connect to OneDrive/SharePoint (works the same way). Make sure you set up appropriate share policy on the folder/file.
Easiest way to get the path is to upload file to OneDrive, open, edit in Excel. Go to File menu in Excel, and right click on the file name. Copy path to clipboard.
Remove "?web=1" from the path.
Source should look like...
Then each user can use their own credential to login to MS account and query file(s).
