Power Platform Community Forum Thread Details

I am building a complicated custom page for my model driven app. I am following the advice from MS here Build large and complex canvas apps - Power Apps | Microsoft Learn where there is a whole section called 'Use named formulas everywhere'. I have tried to build a lot of logic in the formulas but now my whole app is crashing when I tried to make the smallest change to the formula code. The crash looks something like this with the breadcrumb spinner continuously running on the top of the page. The only way to resolve is to refresh the app. If I look at my code in vscode it is about 347 lines. I am kind of stuck now because everything I do causes this crash.

Is there a limit to the amount of logic here or is there something particular that might cause the crash?
