Form editing crashing

I’m using KoboToolbox in Brazil through the global server provided by the site. I’m creating a form for the health area and there are about 15 modules with many, many questions.
When I typed the first modules directly into the Kobo, everything was going well; then when the form started to get big, the page took a long time to load and it froze a lot when adding more questions and adjusting any settings (question order, typing the description, setting the question name and the skip logic).
Before, I thought it was my laptop (Intel i5 9th gen, Nvidia GeForce GTX 1650, 8GB RAM, 128GB SSD + 1TB HD), so I used one of the computers of some friends from the quantum information group at my university, they are great ThinkCentre computers, but it still froze a lot and they simulate quantum computers there and several other processes in the area of ​​materials physics, quantum mechanics, statistical physics and mathematics! This is a little funny because it doesn’t crash in the simulations but it did crash with the Kobo. Now I’m using my aunt’s notebook (intel i7 9th, nvidia geforce gtx1660 ti, 16 gb RAM, 512 gb SSD) and I’m having the same problem, it’s getting in the way of my work because I have deadlines to meet and I simply can’t edit the form without having problems (there are still 3 huge modules to insert into the Kobo). I don’t know what to do. Thank you in advance.

Welcome to the community, @hannahalencar! Could you kindly let us know the total number of questions and choices your form has (in total)?

There are 725 questions in total, but I’m not sure about the options because there are open-ended questions, questions with only two options, questions with only 4 options, questions with more than 4 options, and up to 20 options in a single question. There is no pattern in the options, as there are several types of questions about different things (food, access to health care, chronic diseases, water contamination, etc.). In fact, some of these questions are just grades, so I think there are fewer questions in total. There are still about 200 questions left to be added.

Now there are 920 questions. I’m not finished yet

@hannahalencar, you may need to share with us a screenshot of the app crashing so that we could understand your issue pictorially and be able to help.
