facing the same issue. It works fine when connected for the first time, but on the second attempt, it stops working and shows the error mentioned above
I had this issue when the data wire was connected to the wrong pin on my WT32-ETH01 board. Also have to make sure the Data GPIO value is correct in LED & Hardware setup.
You probably are using a LED output pin that was robbed by the audioreactive usermod, go to usermods and set all pins for AR to Unused.
Weird, I encountered this as well. I confirmed I wasn't using a pin conflicting with audioreactive usermod. But after a couple reboots the problem went away...
"TypeError: Cannot read properties of null (reading 'classList')" is a HTML interface problem and means that the JavaScript code in WLED's UI tried to fetch an element, and then tried reading the .classList property of it. But the element was not found, therefore null was returned. And it's impossible to read a property of a null object.
In short it just means that code was trying to fetch an element and read its properties, but the element with such an ID did not exist on the WLED HTML page.
I am sure we can close this because there's no such issues in WLED 0.15.1 which is currently in release prep at #4701.

Fixed with https://github.com/wled/WLED/commit/2f31ff047d04546595cc7fd996bc04c56e575ffb
The issue is still present defining WLED_ENABLE_DMX in both 0.15.0 and 0.15.1 versions.
