Black window when launching InDesign 2021 on MacOS Catalina
This issue just began today for no obvious reason. On launch, the main ID window remains black and never populates. I've deinstalled\reinstalled and removed preferences twice, but the problem persists. Trying to open an existing file results in the error prompt:" Cannot handle the request because a modal dialog or alert is active". Other than the black main window, no other windows are active
Other CC apps like Lightroom and Photoshop are still fine.
There is supposed to be Chat support, I'm in France at the moment, but I can't see how to activate it. The Vitual assistant does not appear to accept any data input.Any help there would also be appreciated.
Many thanks
Andrew
