I closed all the part and only assembly file left and get this mesg : one of the component of this assembly is in the rollback state - the assembly is not accessable - I can't find the part and save the assembly - not sure how to find part in the rollback state? all icons is gray out

Any help, pls.

EDIT:

I posted this question few yrs ago and still couldn't get the solution for this problem

It's not consistent and hard to replicate. Most of the time, I rolled back some features in part and switched back to the assembly without a problem. Once a while, I got this mesg
