Cannot Combine Adobe PDFs through Context Menu

I have Adobe Acrobat Pro DC and when trying to use the right-click context menu to Combine Adobe PDFs into a single file, Adobe Acrobat DC opens up, but nothing happens for 1-2 minutes. This will happen whether I select one file, multiple files, a small file (100KB<) or a larger file (>2MB). I need to combine PDFs as part of my daily duties, and waiting literally hours every day to combine my PDFs is horribly inefficient.

Versions: Adobe Acrobat DC Version: 21.007.20099, running Windows 10 Pro Enterprise (GC) 1803.

One would expect that the 'combine files' would work quickly for 200Kb files, but it freezes Windows Explorer and crashes if any interaction is made with it.
