MapControl crashes with zoom level > 4.5 and MapStyle.Road

Describe the bug MapControl crashes. This issue started to happen a few hours ago, out of nowhere (Nov 17th midnight UTC). It happens locally when debugging (see demo project below) and all my live apps for seemingly all my users! Developer dashboard reports the crash as: fail_fast_fatal_app_exit_c0000409_bingmaps.dll!mapcontrol::detailtexturesource::begingettexture

This is an excerpt from the crash in the Event viewer:

Faulting module name: ucrtbase.dll, version: 10.0.19041.546, time stamp: 0x73123758

Faulting process id: 0x2c24
Faulting application start time: 0x01d6bca21d0101fa

Steps to reproduce the bug Use the MapControl in an app. Use the Style “Road”. Zoom in past zoom level 4.5 (either programmatically or manually) –> crash

Expected behavior No crash

I got this message from Microsoft:

Hi Moshe,

Upon investigation, the Bing Maps UWP control was inadvertently unable to handle a certain condition around the tiles. To mitigate this issue, our Product Group has initiated rolling back the change that impacted this experience. This issue should be beginning to resolve within the next hour, if not already.
