We just posted another pre-release of Processing 4!
Includes OpenGL updates, video working again on macOS, and lots of other fixes for reliability (link at the bottom of the page): https://processing.org/download/
Please test this… all bug fixes will be happening in the 4.x series, and on macOS, it will increasingly be the only version that actually runs (due to Apple’s security/OS/hardware/deprecation changes).
