WebGL not running on D&D Beyond (update Thread)

Description of the issue:
WebGL not loading on D&D Beyond character sheets for dice rolling. Loads fine on other websites. (This is an update to a previous thread which closed about this issue.) I turned off Hardware Acceleration and it seemed to start working, but it is exceedingly slow.

Exact URL of the website in question:
D&D Beyond Character Sheet

Did the issue present with [default Shields settings]
Yes

Does the site function as expected when Shields are turned off?
No. But Shields seems not to break anything else on the site.

Is there a specific Shields configuration that causes the site to break? If so, tell us that configuration. (yes/no):
Only dice rolling is broken irrespective of Shields configuration and being up or not.

Does the site work as expected when using Chrome?
I installed Chrome solely to try and ran into the exact same issue. Dice rolling doesn’t work, everything else on the page works flawlessly.
