Giant void that drowns you in blocks

I signed on and there is a perfect square or rectangle void cut out beneath my base.  This was not there when I signed off the previous night. I glided into it and I immediately started to die (Drowning).  It said I was drowning but I was not in water.  It seemed like I was in the middle of solid blocks. 

 

I confirmed this by building blocks beneath me to get out of the void.  When I built It revealed the block  I was stuck in similar to when gravel collapses on you and you take damage.  Once I used my pick axe to break the block I was in  I would stop drowning and be ok. 

 

If I were to step one block over from that position it would do the same problem as if I was completely surrounded by blocks I couldn't  see again.

 

Although i could see my supplies I could not pick them out.  I ran over them but it wouldn't  register. I lost all of my armor and netherite tools and Elytra.
