Restore just one application from Time Machine

Hi there,

I recently updated an application but it's frequently crashing and I'm looking to downgrade. If I restore an older version from Time Machine, will that cause issues if there are other pieces scattered around my system?

Should I experiment? That is, try the restore, and if there are issues, revert the restore by restoring to the latest version (via Time Machine or by reinstalling). Or would this muck things up even more?

The application in question is PDF Expert.

Thank you community.

P.S., I'm aware of the below thread that addresses this question, but the advice is fairly dated, so I thought I'd check again
