Adobe Acrobat Pro DC crashes when I combine PDF's

I recently installed Adobe Acrobat Pro DC on my computer and every time I try to combine PDF's it says that Adobe has stopped working and crashes. I have uninstalled and reinstalled, I have done all windows updates, I ran the Adobe Acrobat cleanup tool, and all of the Adobe updates are up to date. This issue is extremely annoying and it really hinders my work, as I constantly need to combine PDF's (sometimes multiple thousands of pages). This has never been a problem in the past until about 2 weeks ago. I appreciate any and all help!
