you mention ‘data is pulled from a database correctly’ suggesting you have a ‘connection’ to another database. Perhaps that action isn’t being totally completed and is in a ‘loop’ for some reason. Check your connection agent log files as this may show some additional information and also your database log files as well.
but also if you see this in ‘preview’ .. you could run the form in ‘debug’ mode as well and then you will be able to see all the events running as the form is opened and that may also show you a function that isn’t completing correctly
and finally, ‘started yesterday’ .. if you have added anything to the form since ‘yesterday’ .. review that work as it could also be related
