InDesign Crashes on quit with SmartStream Installed

[KeanVarvel]

Hello HP Community.

InDesign crashes whenever I quit. But only after exporting a PDF with SmartStream Designer installed.

I can use SmartStream all day without issue, including outputting imposed and variable files. Then quit InDesign and no problems. But as soon as I export a PDF from File>Export. Then I know it'll crash when I quit. Even if I open InDesign (fresh), create a new blank document, export a PDF (any settings), then quit InDesign, it'll crash, every time, without fail. Even if I don't touch SmartStream.

However, if I remove the SmartStream folder from the InDesign>Plug-Ins folder, the issue goes away. I can then work in InDesign and export PDFs all day long without issue. Put the SmartStream folder back and InDesign again crashes after exporting a PDF and quitting. This is repeatable every time. Occasionally, InDesign will reset my Workspace after crashing so many times.

I have uninstalled, reinstalled, even reformatted my SSD. Fresh downloads and installs all around, from the OS up and still have the issue. It's been this way for years, even through older versions of InDesign and SmartStream. I keep thinking that maybe the next version will work, but it never does.

It's more of a nuisance than anything else, but also a sign that something's not right.

Here's the first part of a Crash Report... If the remaining portion is pertinent, I'll post.

FYI. I worked with Adobe and they installed SmartStream and had the same results. So I know I'm not the only one.
