Problem powering ESP32 with buck converter

AITRIP 3PCS Type c 30pins CP2102 ESP-WROOM-32: https://www.amazon.com/dp/B0CR5Y2JVD

DC12V/24V to 5V 5A 25W USB C Step-Down Converter Buck Module Power Adapter: https://www.amazon.com/dp/B0FVG5VW36

When powering the ESP32 from the buck converter, the red light comes on, but it never connects to wifi. If I power it with a USB cable from my computer or a generic USB power adapter, it boots up, connects and works just fine.

I have been reading about problems with soft start on the buck converter. This one is sealed, so I can't modify it.

Does anyone have a suggestion on how to power the ESP32? I need 12v as I'm going to use it to control some PWM fans.

Thanks!
