IPhone 6 Brave App Crashing

Been using Brave on my iphone 6 for several months without a glitch. Today it just keeps crashing as soon as I tap the icon. IPhone software is up to date. Last Appke update was like a month or so ago. I did a soft and hard reset on the phone to same problem appearing. Trying to avoid having to delete & reinstall app because I dont want to loose all my saved searches which I keep as a file.

Brave will crash, but if I do a double click it appears as a background app up and running. Then if I click on it it just tries to come up for a second then just crashes again and again.

Any ideas? What happened overnight?
