Planner Not Loading (Blank Page) - Grid View Crashing On Chrome

Hi all

I use Chrome and in just the last 24hrs, Planner stopped working as it was giving me a blank page when I loaded the URL. After investigating the console and trying Edge, incognito mode, deleting cookies/cache/data etc., we saw that the Chrome Developer Console reports 

"Uncaught ReferenceError: Cannot access 'B' before initialization at Module.CanvasUserTasksGridView"

specifically within the 

"planner-canvasusertasksgridview component"

We've confirmed that Board view works normally in Chrome, and the same plan and Grid view work correctly in Microsoft Edge. 

Additionally, Chrome is attempting to load some Microsoft Office font resources using malformed URLs containing a duplicated protocol, such as 

"https://https//res.cdn.office.net/..."

which then fails with

"ERR_NAME_NOT_RESOLVED" 

This makes it look like an issue with the Planner Grid component or its Chrome-specific resource loading rather than the plan or account itself.

I will continuing using Edge for the meantime, but if there is a fix or workaround as we mainly discuss tasks in grid mode in meetings so it would be great to get this back working in my preferred browser. Any help would be great!
