Suddenly bulb app stopped working on my iPhone x

Greetings community,
so this is what actually happened, it was working all fine and here’s a thing, I had been
stalling the ios upgrade as it takes a lot of time to reboot and all but in this morning, I did the
update and I found some apps including bulb app stopped working. when I enter the
app I get random crashes, this has never happened before please guide me.
