Crash after using UMG (More details here)

Development Programming & Scripting UI

So I added an animation to my widget and this animation is enabled and disabled using a variable in the ‘FirstPersonCharacter’.
I’m using start animation and stop animation with a few branches.
After trying to figure out ways to stop animation without it staying visible, UE4 crashed. Twice.
I’m using 4.8.2 as my college has that version and they’re not upgrading until next year. I have to get this game done by March and need help urgently.

Here’s crash log:

Hi HashtagPulse,

This appears to be same crash we had reported as UE-17971, which was fixed in 4.9. If you’re using a source build, you could integrate commit found here. Otherwise, assuming it’s same crash, you’d need to avoid changes you made that started crashing, or revert to an earlier version if that’s not possible. notes in our crash report indicate that it may be related to Visibility property from Sequencer, so I’d start there.
