New LED’s stopped working properly

Hello, I recently was gifted a wall art sculpture that uses LED’s. The device worked fine for the first few hours but when I went to test it again before it hanging it up only the first couple LED’s come on, usually either a white or a white and green. It uses WLED which is how I found this forum, I don’t have experience using LED controllers so I’m looking for some help.

I’ve tried holding down the reset switch which doesn’t seem to help
