Where Does macOS Store Resume Data?

Short version is that I am wondering where macOS stores the list of open applications when a user logs out, such that they can be restored when the user logs back in (as part of macOS' **Resume** feature)? For context, the reason I'm looking for this is that I believe I have an application that's "stuck" on this list, as when I turn **Resume** off the application (along with all others) no longer reopens on login, but when I reenable the feature it starts reopening again and I'd prefer that it didn't. My best guess is that whichever file stores this list is somehow not updating properly (perhaps it isn't writeable for some reason?) but that disabling the feature bypasses it, however when reenabled (as I would like it to be) the problem returns because the application is still in the file somewhere.
