Is anyone else getting memory errors when using component properties?

I created what felt like a simple component set with properties and variants to test it out yesterday. Today when I tried to do something as simple as deleting one of the variants, my memory exploded to 100% and the file crashed. I went back to the example from the component properties playground and the same issue is happening there now too.

I have no idea what happened, but its completely unusable for me. Is anyone else having this issue?
