WebGL: 2D and 3D graphics for the web - Web APIs | MDN Means your PCs graphics couldnt handle it. Outdated drivers, specs too low, etc
Then something on your PC changed. Windows update, drivers of the GPU updated or changed, something. Its essentially a computer problem (CONTROL ask GPU: "hey can you do WebGL so we can start loading the 3D view?". GPU says "no can do". CONTROL has to abide and stop loading 3D view, and tells you thats what happened in the log...)
so ya i hooked up my old laptop and it works just fine it just seems to be on the one i control my CNC with. This pic is what I've been using for over a year it has windows 11pro
Update all drivers, all updates to windows. Maybe needs a clean install. Maybe something else you installed recently caused conflicts, really no way of knowing
