I use a Wacom to draw my art on Adobe Illustrator 2019 cc, 23.0.6 64 Bit. I haven't had any problems drawing, but today I am only able to draw a few items before the art board completely freezes and I can't draw anymore. HOWEVER, when looking at my layers, everything I draw shows up. I just can't see it on the actual art board. The things I was able to draw, I am unable to move or change. Then trying to fix it, the whole art board disappears, but it still says it there on the Layers tab...

Please help me.
