I am writing this to potentially report a bug.
I am running Version 2.6.4 of Survey123 Connect, and it runs perfectly fine when I create and run surveys locally. As soon as I log into ArcGIS Online (AGO) and open my existing survey, Survey123 crashes.
At first I thought this had to do with certain fields that I had added, but this does not seem to be the case.
I have attached the three log files that all represent attempts to login withing minutes of each other. The smaller files seem to indicate why the program crashed.
