Asset import freezes both importer and Design Studio

I wish to import my company Figma design, without subdividing it in smaller parts. However, while importing a Figma design via generated .qtbridge file. It loads and freeze systematically at 54%. This happen on both 3.9 and 4.0. 

Can't upload qtbridge as is since it contains copyrighted material , however I should be able to share metadata if required.
