As a test delete all your relevants and see if it still crashes. This was happening to me because I was hiding 10 fields that were large select_one lists. I could hide like 6 - then at 7 it would crash. I had to unhide some until it stopped crashing.
Just a guess since your form is huge. You may want to consider putting the 1-8 sections in a repeat if your schema allows.
Thanks Doug. It does seem like the size of the form has something to do with it. I deleted all relevants, but it still crashes. I tried deleting the second 1-8 section to bring the total lines from 330 to 200(keeping relevants), still crashes.
I am having a similar problem, whereby the survey (created with Survey123 Connect 3.3.51) works on my laptop (lenovo Windows) but crashes at certain questions within the survey when trying to use it on an iPad. I have been able to add 54 records with a windows machine but can not add one record with iOS iPad to the same survey.

I have removed the Repeat_Count references as mentioned in other posts, republished and it is still crashing on iOS.
Yes still happening for me, it seems that it has something to do with size or how much is hidden by relevant statements. I get the survey working and then add a section or a couple of questions then it crashes again.
