DataSource.Error: Web.Contents failed to get contents

Hi Thomasino, this is the exact same problem I am experiencing almost down to the letter. I had Power BI desktop reinstalled a couple of weeks ago. The only difference with mine is that the SharePoint list I cannot connect to doesn't have lookup columns. I can connect to other lists on the same SharePoint site. However, I cannot connect to this particular list along with another list, which is a replica of the same list, but with formatted choice columns and some additional text and number columns. 

The Power BI server version of the same app is also not refreshing the datasource and calling a similiar DataSource.Error / Web.Contents error. It refreshed successfully back in March 2023. 

I am hoping if I reinstall the March Power BI desktop version and republish the app to Power BI server everything will work.
