fix invalid tooltips freezing client

[micsthepick]

add a simple try catch

• should fix cases where the tooltip is not able to render - besides, what would there be to search for if the tooltip is simply broken?
• idea: add a way to search specifically for items that have broken tooltips - not technically necessary once this fix is in place, but could be nice to have

[micsthepick]

to be clear, all this pr does is add the try-catch, and doesn't add the second bullet point's idea.
