Indesign unable to launch on macOS 10.15.7

[tonylibby]

Am running Indesign on an IMac and the opening sequence has been getting slower and slower until it has now shown me just the spinning ball and Indessign will not open.  I have to 'force quite' to get away from the spinning ball.   Indesign is up to date and the IMac is 10.15.7

Can anyone assist

How much RAM and spare disk capacity do you have?

It might be worth resetting your InDesign preferences.
