MacBook Air 2019 display blacking out during use

So today i went to my office as usual.

im currently using a macbook 2019.

today, the macbook suddenly started blacking out miduse.

the display was on, along with the backlights of the keyboard.

but the display was showing black.

The only way it went away was to close and open the lid.

it isnt sleeping, it’s just displaying black.

i have reset SMCE and NVRAM but so far no luck.

it also happens in safemode but im still trying to reinstall macos from recovery mode in case the driver files are corrupted

the issue also goes away for an hour or so if i leave the macbook powered of for a few hours.

Any idea what the problem is?
