So sorry to hear that you are facing issues with InDesign. Font issue was reported in one of our earlier releases and was fixed in November itself. There could be multiple reasons why an application would crash. I would request if you could create a new thread along with the following details:
Exact version of InDesign and operating system.
When did this start happening? Are there any recent changes made to your system? For example, any antivirus, system updates or web extensions installed recently.
Does it gives any crash report? If yes, share it by following the steps shared here ( https://helpx.adobe.com/in/indesign/kb/submit-crash-reports.html ).
If you are on Windows machine, check for error related to InDesign in Event viewer.
