InDesign Keeps freezing - Any ideas?

I had the same issue, noticed the freez happens when I choose a font, 

I solved this by deleting all fonts I have from fonts directory, then installed only the fonts I use and from reliable source.

This fixed the freezing problem for good.

Good luck 

When you uninstalled and reinstalled did you do it in the following manner?:

In the app section of your Creative Cloud desktop app click on the “V” next to the app’s (InDesign) name and choose the “Uninstall” option from the pull-down menu that appears. After you’ve run the uninstall then use the Creative Cloud Cleaner Tool Use the Creative Cloud Cleaner Tool to solve installation problems  . Then reinstall the program through the Desktop app. Before you reinstall, trash all preference files (see instructions below) to make sure that your install is completely clean. Then launch InDesign and see if the problem persists.

To trash preferences:

For Macintosh Users: The User Library folder in which InDesign’s preferences are stored is hidden by default on most Macintoshes. To access it make sure that InDesign is closed and click on the desktop to launch a Finder Window (Command-N). With this window in column view follow the path User>Home folder (it’s the folder with an icon that looks like a house—it may have the user’s name rather than “Home”) and click on the Home folder. With the Option Key pressed choose Library from the Finder Go Menu. “Library” will now appear within the Home folder. Within the Library folder find the folder called Preferences and within it find the folder called “Adobe InDesign” and the file called “com.adobe.InDesign.plist” and delete both that folder and that file. When InDesign is next launched it will create new preference files and the program will be restored to its defaults.

For Windows Users: You can try the quick way of resetting on a PC which is to hold down Ctrl + Alt + Shift when launching InDesign and respond affirmatively when asked if you want to reset. There have been some recent reports that the window asking if you want to reset is not popping up but that the prefs are being reset anyway. If this works great but if it doesn’t you may have to manually delete them.

To do so:

On Windows 7 and above the preference files are hidden. To find them go to the Control Panel and open Folder Options and then click the View tab. Then select “Show hidden files and folders” or “Show hidden files, folders or drive options” in Advanced Settings. Then delete (or rename) the folder at the end of this path: C:\Users\<USER>\AppData\Roaming\Adobe\InDesign\<Version #>\<Language>. Make sure that InDesign is closed when you do this. When you relaunch the program it will create  new preference files and the program will be at its default settings.

The advantage of manually deleting preference files is that after you’ve reset up the program (make sure that no document window is open) to your liking, you can create copies of your personalized “mint” preference files (make sure that you quit the program before copying them—that finalizes your customization) and use them in the future to replace any corrupt versions you may need to delete.

Same here on Win10. I have this on my two Win10 machines. Happens always when I'm selecting the text tool and choose a font. After a few times quitting it manually via task manager, it works. But it's hardly annoying and makes working with it very hard. Oh and it really keeps freezing, it doesn't work after a few minutes (like it was before). No the only way I can quit is via task manager.
