Alternative option for led light

i need help finding a replacement light for light fixture model 21000wv-bz-clover.
the rectangular led in the fixture measures about 10 1/2" L x 3 1/4" W x 1.2mm thickness.

Most light fixtures use custom made LED plus driver PCB assemblies, this looks like a PCB assembly that only the light fixture manufacturer can supply.

Unfortunately the manufacturer has closed down. I don’t need an exact match something close enough that can work. Thank you

Not knowing the specs here are some similar size parts.
Optoelectronics | LED Lighting - COBs, Engines, Modules, Strips | DigiKey, there is no direct cross.

Are you sure it’s not just the distributor that has closed. The PCB is marked as if it is part of a light from G&G Industrial Lighting.

The board in the picture is 120VAC input, only one item in the search is 120VAC and its data sheet shows it a complete assembly with housing not a PCB assembly.
