CEP: showOpenDialog

Just use 

window.cep.fs.showOpenDialogEx()

with the same parameters and you should be good.

I have a similar issue. For me the file open dialog crashes on CC 2019 (both tested with After Effects and Premiere Pro) and works fine on CC 2018. The suggested workaround to use the jsx functions for files and folders works fine. Thanks for sharing this solution!

This is the exact code that is crashing for me

var allowMultiple = false;
var chooseDirectory = true;
var result = window.cep.fs.showOpenDialog(allowMultiple, chooseDirectory);
