I am using Intel hd graphics 4000 and just updated its graphics. But the problem still persists.

The error window gives you a solution already. You got to launch godot with --rendering-driver opengl3. Note, you don't have to do it via command line, you can also create a shortcut to godot exe and edit the properties of that to include the argument in there.
Anything Intel HD is old and most likely won't support Vulkan or at least won't support it well. Intel Xe will likely do better here as it's newer, but that's not the graphics you have in your system, so...yeah.
rajhansarah I think you can also change to GLES2 in the editor as well once it launches using @Megalomaniak 's method? GLES2 tends to work on older systems much better if my reading is right?

Pretty sure GLES2 is essentially OpenGL 3 so...the same renderer.
Godot 4 uses GLES3 the GLES2 renderer was dropped. But yes, it can work on old video cards with the command line flag.

Megalomaniak thanks for the clarification. This is the technical stuff my dumb humanities-trained brain misses. 
SnapCracklins To be fair, the naming scheme doesn't help. They could have named the first GLES '2' from the start so it would correspond with the desktop GL 2.1
