WhatsApp closes automatically on Lumia 735, what could cause this?

[Windows Central Question]

I have installed WhatsApp on my girlfriend her brand new Lumia 735 (Windows 8.1 update 2). WhatsApp is important to her as she uses it very frequently. She seems not be able to open the app as the app closes automatically and I have not been successful in resolving this issue. I have tried to find a solution on the internet but I couldn't find any solutions.

I have downloaded the app from the store and installing and verifying does not cause any problems. I receive the text message to verify the account and I can enter the code. When it moves to the next screen, where it asks for the users name, the app closes automatically. I have deleted the app and re-installed it which did not help to solve the issue. I have restored the phone to factory settings and this did not help either. I have run out of ideas and she seems to be frustrated about the switch to WP, any ideas what I could do to get WhatsApp running on her phone?

Thank you very much for helping.

Is WhatsApp installed on phone storage or on a SD card if its on the SD card try on the phone storage.

Exactly the same problem here on a Lumia 925 here.

Install WhatsApp in phone memory and try not to restore your backup hope this works for you...

thanks for replaying!! 925 has no sdcard option. I choose not to restore the backup. Same result

Try this. Uninstall whatsapp. Go to settings > backups > apps+settings>manage backups> only check the app backup and delete. Reinstall whatsapp after this and it should be okay.

Thhanks guys, gotta say that finally we could finish the installation, pressing very quickly next next next before it crashed. No sometimes it opens and works fine and somtimes crashes...I little bit dissapointed with something as essential as Whatssapp.
Before that I also installed thw windows 10 preview but same result and worse, lots of crashes around. Now on 8.1 only Whatsapp crashes.
Are you having the same troubles?

hi guys, I flashed a rom (without the telephone company layer) and bammmm gone! Now it works like charm, never had other problem, and it runs smoother!
