Is there any way to change file size to allow me to upload a file?

You can't change these settings in SharePoint online.You can change the file size upload limit in an on-premises environment, but it's not possible in SharePoint Online because it's a shared setting for all the tenants.

Answer 2

Your issue is related to the internet speed of upload. I had the same issue, tried multile times using my home internet, didn't work. Tried my phone data and it worked like a charm.
