Roll back from 4.14.2 to 4.14.1?

Hey guys, how can I roll back from 4.14.2 to 4.14.1? Because, for me I can not import FBX any longer without getting a crash after the update. I cant even re-import stuff that was imported originally from the same FBX files that were imported before.
Please help ! This is a real game breaking hold up.

I have the same issue with 4.14.2

Hopefully they fix it rather soon.

There is a QFE fix you can download for the mesh importing crash.

The hotfix for this will be out soon, but Github users can grab the fixed file right now.
