to clear preferences and caches you could visit the respective Version 17.0 folders in your personal User folder and delete them. Before do a backup. E.g. zip the folders. InDesign will rebuild them when starting the next time and launches with default values.
Preferences is at:
user > your user name > AppData > Roaming > Adobe > InDesign > Version 17.0
Caches is at:
user > your user name > AppData > Local > Adobe > InDesign > Version 17.0
To see the AppData folder you have to enable the file explorer to see invisible elements.
