InDesign Character and Paragraph panels not working

[crooksdesign]

I have an issue where my Character and Paragraph panels now don't display any information.  The Paragraph panel stopped working a couple of weeks ago and my Character panel stopped working today.

I can highlight the text and the properties show in the top panel (when in Essential Classic view), but the individual panels remain blank.

Try to reset preferences: quit InDesign and relaunch it while holding down the Shift, Ctrl and Alt keys [Windows], Shift, Ctrl, Alt and Cmd keys [Mac] until you see a warning message asking for confirmation.

Standard troubleshooting would be to delete/rebuild preferences: https://creativepro.com/rebuilding-indesign-preferences/

Or, clear the caches, see Bill Silbert's 2nd post, not the one marked as correct answer (which was for deleting preferences): https://community.adobe.com/t5/indesign-discussions/need-to-clear-indesign-cc-2019-cache/m-p/1052374...

UI problems are often Cache related. You might try deleting your Caches folder before Preferences— if it’s the Caches you won’t have to rebuild your prefs.

Thank you Rob - This worked.

What helps me, because it sometimes happens to me too, is to double-click twice on the title of the palette (i.e. the window closes once and the next time you double-click, the window appears again - and its contents).

In the lastes InDesign this is happening at least once a week, on multiple computers.

We have trashed both Caches and Preferences and it only last a day or two. Then Panels start corrupting and within a day or say Indesign will shut down with a Serious Error.

Others havng this issue?
