Version 3.4 locks up on 2017 imac
I have installed, uninstalled (back to 3.31), and reinstalled version 3.4 on my iMac 2017 and 3.4 locks up when it attempts to "prepare a scene" (White background only).
In an attempt to make sort it out I created a new simple project in 3.31 using Dr. Applesmith, installed 3.4, which then attempts to open the last opened project and it worked for a short time but when I then opened a previous other project it locked up again.
It appears all other new Adobe apps (PS, PP, AE, AU) are working.
