My resourcepacks aren't working properly.

I'm not sure what's the problem. I tried to find solutions via Google, but I couldn't. I can see and use my downloaded resourcepacks. But when I use it, it doesn't work. Also, the RTX shader is broken, too.

My specifications

CPU : Intel Core i5 13400F
VGA : NVIDIA GeForce RTX 4060
RAM : 32 GB DDR5 Bus 5600
Storage : M.2 NVMe PCIe Gen 4 2 TB

Lastly, I'm sorry for the weird audio.
