Hey all,
I was building an app yesterday and it was all working fine.
Today I want to use the app but it keeps crashing on Chrome with error code result_code_hung. On firefox it is extremely slow and laggy, but eventually the UI updates correctly.
It happens when I select a table row that triggers multiple queries to run.
My main concern is how to debug this?
There have been similar descriptions before, but apparently they have been resolved: Retool Unresponsive Page - #12 by PeteTheHeat
Hey @ErikLT - welcome to the community and thanks for reaching out! 
This sounds less than ideal. 
Are you still experiencing these kind of crashes and long loading times? The first thing I'd have you try is to disable the WidgetGrid feature via the bottom toolbar.
It seems to be a very rare issue but a handful of customers have reported that this causes certain queries to time out and ultimately crash. We scaled down the rollout of the feature, as a result, so it might have already been turned off for you.
The other thing I would recommend is disabling all your browser extensions to see if the issue persists. I think this is less likely to work, given you've reproduced similar slowness in various browsers, but it's still worth trying!
