Hello. I am sorry for the late reaction.
Do I understand correctly, that the issue does happen, when the website is loaded during every launch? In that case, there are a few ways I would recommend trying to solve the issue.
1) Disconnecting the internet
If you disconnect your internet before you start the browser, it is possible, that the website won't load up to the state, that will cause the crash. After that, you could close up the tabs, and reconnect the internet.
2) Reinstalling the browser
In case, that you do not have too many important information save up, uninstaller does allow you to reinstall without saving the user data. That should definitely fix the issue, but I would recommend it only as a last option.
I am now going to try to recreate your exact issue, but I still wanted to offer these solutions, just in case the first one worked.
I hope we will be able to solve this soon.
