OpenGL Depth buffer Issue using Silk .NET #2611

I have got this error for Model Loading from OpenGL Tutorials and this error might be related to Depth Buffer or indices and whenver im tryng to get the buffer size for GL then it's shows Maximum value of int instead 8,16,24 etc. Please look into this. I got this same issue in Vulkan (vkguide ) C++ where it's related to depth buffer and it was to adjust the depth attachment and depth buffer but OpenGL handles everything and i enabled DepthTest etc and it's still showing this error.Please look into this
