1.6.6 Unstable on my Mac

[TNGEO]

I updated to Scribus 1.6.6 on my mac studio (Tahoe 26), and find it unstable. I closed the program, installed it, rebooted my computer. Now, when I paste images in a text box the whole page goes blank, as do following pages. They come back in flitty ways, not conducive to document development and editing. Is there a bug fix for this yet? If not, I will try to reinstall the previous version.
