M1 Battery Not Charging via Thunderbolt

Hello, I have Philips 279P1 external monitor connected solely by a Thunderbolt 3 cable to my MacBook Pro (13-inch, M1, 2020). It is supposed to provide enough power for the MacBook to operate and charge its battery, which it has for the past few months.

Today, I am not able to get the MacBook's battery to charge with this setup anymore. The screen acts perfectly fine as a secondary monitor with both image and sound, but alas no charging.

I have tried the following to no avail:

Closing any apps that consume too much power.
Restarting the MacBook.
Shutting down, waiting a few minutes, and rebooting the MacBook.
Disabling the "Optimised battery charging" options in preferences.
Restarting the monitor.
Resetting the monitor to its initial settings.

I'm on macOS Monterey v12.0.1 (21A559)

Any ideas as to how I can resolve this?

Thanks in advance.

I would power the Mac directly with the appropriate charger, this will bypass any issues.
