Getting Error: Failed to link shader program. Error: Internal error compiling shader with Metal backen

This seems to be the same problem.

[SOLVED] Failed to link shader program on 1.64 - Safari 15.1

Hi, Engine Version 1.64.0 and 1.64.1 give me the following shader error on startup of the Editor and built apps, resulting in a black screen: “Failed to link shader program. Error: Internal error compiling shader with Metal backend.” [Screenshot 2023-06-30 at 16.16.45] System: macOS 12.0.1 MacBook Air M1 Browser: Version 15.1 (17612.2.9.1.20) If I switch back to 1.63.6 or to “Prefer WebGL 1.0” everything works fine. I guess a macOS/Safari upgrade will fix the issue, but it seems to break…
