Usually DDNet has a strong fallback system for Intel GPUs on Windows as they often caused bugs with OpenGL 2.1+
If you have a recent Intel GPU you can simply switch to Vulkan in the graphic settings inside the client.
Else type gfx_gl_major 2;gfx_gl_minor 0; gfx_backend opengl
in the F1 console of the client and restart.
