I’m still seeing this issue in Unity 6000.0.60f1. The shader errors appear when building a URP project for WebGL, and the problem causes players using older 32bit browsers or lower end devices to be unable to run the game. Is there any known workaround or planned fix for this version?

Happens to me as well. The error disappears if I disable "cast shadows" option when building for WebGL.

Can confirm. Broken with Unity 6000.20f1and freezes the browser (Chrome) on Windows 10 with an RTX2080Ti GPU.
However, the build does work on Android with the Firefox browser.

Repeats on macOS Sonoma 14.6.1. Here the WebGL player screen is black, the game does not launch on any browser.
