Updated Citra and now my games won't work

Citra was working fine, updated it and now my games (fire emblem fates and fire emblem awakening) crash, is there anyway to revert back to a previous version of Citra?

go here https://citra-emu.org/download/

click on manual download and choose nightly or canary build (canary is recommend for more features, namely performance)

Bisect it to find the exact build that causes the crash. Download the build manually from the site and find the one that started the crashing.
