Hi Jason - works here… I changed the text that is normally shown as “<>” in Properties - correct? Does this happen in a new file? If not, can you send us a file that shows this? Are you using a non-default annotation style?
It does not matter what file I use. I have made a short video on what I am seeing.
This was a fresh document where I made a simple cube and when straight into layout.
I place a dimension, set the style, and change the dimension. Clicking back onto the layout crashes the document. I have repeated this 100% of the time. It does this for all default and custom styles.
