Oof, sorry to hear that. I hope they'll send you another board. Wish they'd keep a store open and put their stuff up for sale instead of group buys

I saw some talk on the discord that a major ESD will probably kill the LEDs but the rest of the board should come back by flashing firmware again.

What you can do is download qmk toolbox, and grab the binaries/hex files from the graystudio space65 r3 discord channel. They have instructions there for flashing. If you've never done this before look it up on youtube or feel free to DM me and I'll give you a hand.
