Trying to install Sequoia, however it always ends up giving me a prohibited sign shortly after attempting to boot.

PC Configuration:
Ryzen 5 7600 6-Core Processor
DDR5 32GB 6000MHz CL30
Crucial P3 Plus SSD
ASUS ROG Radeon RX 6650 XT 8GB

OpenCore Log
EFI folder
 
Your USB map must be wrong if you are still seeing the prohibited 🚫 sign. As that is normally what shows when the USB pen drive is dropped by the installation process due to incorrect USB mapping, or more commonly there being no USBMap.

If you add -v keepsyms=1 debug=0x100 boot args to your config.plist, what is shown on your screen? Post a photo or video of the verbose text.
