After updating to 1.21.80 ray tracing is now broken, I primarily build in Marketplace’s RTX maps like medieval. And all other RTX maps like neon city. Emissive blocks no longer work, light sources pulse, sunlight only one working properly.

If this doesn't work, delete your options.txt in \AppData\Roaming\Minecraft Bedrock\Users\6531558760343982738\games\com.mojang\minecraftpe. This fixed it for me finally! Also fixes very bright vibrant visual issues.
