title: Blender Eevee render not working properly
body: <p>So I am new to Blender (v 2.91) and I was trying out these render options i.e Eevee and Cycle. The Cycle (only CPU) option works fine for me but in the Eevee option, the cube/object appears black or sometimes disappears (As shown in the screenshot below).</p>
  <p>I am not sure why this is happening. I tried googling it but didn't get a proper resolution. I am attaching some screenshots for reference also with my current preferences in Blender.</p>
