"(605, 35)-(605, 36) Token comma expected" when creating a new query

I upgraded to the latest version of Power BI Desktop. This is the installer version:

This failed to start because, like others, I was caught out by Power BI Desktop no longer been supported on Windows 7. Aside: it would be nice if the installer recognised the fact and failed to proceed, and if Windows 7 was removed from the system requirements on the download page; these are the system requirements as shown today:

Anyhow, I uninstalled this version and reverted to:

Now I get the following error when I try to create a new query (including a blank query) or view data source settings:

Speculate that the uninstall of the latest version wasn't clean and is preventing the earlier version working.

Thanks for the reply Lin.

I did finally manage to resolve this by:

1. Uninstalling Power BI Desktop from the Control Panel.
2. Permanently deleting the folder C:\Users\MYUSER\AppData\Local\Microsoft\Power BI Desktop [where MYUSER is my username]. This had over 200MB of files in it.
3. Re-installing the September 2019 version of Power BI Desktop.

Figured I'd share with the community in case anyone else hits this.
