HDRI backdrop stopped working


My HDRi backdrop stopped working and it’s driving me crazy. All i did was change the material of the Envirodome named HDRI_MID to unlit for a second than back to default lit and now it’s white and i cannot get it to work. Its not even working in any other scene/project now. I looked around in the material but i don’t under stand anything since i didn’t even build it.

Changing hdri’s doesn’t work or help it’s like something got fryed when i swiched from lit to unlit.

Any help or tips would be really appreciated.

Thanks in advance
