Sketchup on my iPad is crashing

I have been trying to design on sketchup for the past 4 days and sketch up and been crashing every time I erase something. Everytime I try to extrude. It doesn’t respond and then crashing. Doesn’t save it. I am having to design over and over again. But it’s not helping.

Kindly please help me

Is it one specific file that is crashing? And if so can you share it?

Do you get the “what were you doing” bugsplat?

I often get one file that crashes at the same point with the same process attempt over and over. I have to switch to a different operation to try and get past whatever is catching.
