System Used: N/A
CPU SKU: i5-8265U
GPU SKU: UHD 620
System BIOS Version: N/A
CMOS settings: N/A
Graphics Driver Version: 25.20.100.6444
GOP/VBIOS Version: 9.0.1080
Operating System: Win10 Home
OS Version: 10.0.19603
API: OpenGL 4.5
Occurs on non-Intel GPUs?: does not occur on NVIDIA GPUs, AMD not tested

Steps to Reproduce:
-------------------------------
1. Create an OpenGL 4.5 context.
2. Create a framebuffer and try to bind a cube map face to a color attachment

GLuint cubeTex;
glCreateTextures(GL_TEXTURE_CUBE_MAP, 1, &cubeTex);
glTextureStorage2D(cubeTex, 1, GL_RGBA16F, 1024, 1024);

GLuint fb;
glCreateFramebuffers(1, &fb);

glNamedFramebufferTextureLayer(fb, GL_COLOR_ATTACHMENT0, cubeTex, 0, 4);

Expected Results:
-------------------------------

According to the OpenGL 4.5 Spec, no error should be thrown and the operation should be successful

Actual Results:
-------------------------------

With a debug context, the following error is thrown and any drawing operation with the Framebuffer bound will not do anything.

Error has been generated. GL error GL_INVALID_OPERATION in NamedFramebufferTextureLayer: (ID: 3072786610) Generic error

The error is generated by the call to glNamedFramebufferTextureLayer.

Additional Information:
-------------------------------

On any NVIDIA card I have tested, no error or warning is generated

I'm having the exact same error on my UHD 620 card with OpenGL 4.6 context, and no error is generated on my AMD card.
