Hi,
Sorry about the trouble this issue has caused. It is currently under investigation and would need a few more details like:
NFO file (Open System Info > File > Save it Creative cloud and share the download link). Steps to share file via Creative Cloud are shared here.
Logs from Event Viewer. Press Windows+R to open the Run dialog, enter eventvwr (or eventvwr.msc) and hit OK. Go to Windows Logs > Application and check if you see any error related to InDesign.
Share crash logs by following these steps: https://helpx.adobe.com/in/indesign/kb/submit-crash-reports.html While submitting the crash report please use the same email address, with which you are signed in on this community. This will help us find the crash report and help accordingly.
Once done, try following these steps one by one and let us know how it goes:
Remove third party plugins: Open the plug-in folder (Program Files > Adobe > Adobe InDesign > Plugins). Remove third-party plug-ins and paste them to Desktop.
Remove corrupt fonts: Open Fonts folder in Control Panel. Select all the fonts, and copy and paste them in a folder on desktop. Trash the fonts from the Fonts folder. Copy and paste each batch of fonts from the desktop to Fonts folder and launch the application. If you are unable to launch the application, the damaged font exists in the Fonts folder. Identify and remove the damaged font, and relaunch the application.
If that doesn't help, try booting the system into Safe Mode (https://support.microsoft.com/en-in/help/12376/windows-10-start-your-pc-in-safe-mode) and check how it works there. It starts your system so that it performs certain checks and prevents third party software/ services from automatically loading or opening.
If that doesn't help either, login to Hidden Admin account (https://www.youtube.com/watch?v=EfbMs3w-Z3s&t=53s). Check how the application works there. If it works fine there, then it could be related to permission errors. Follow these steps to repair permission errors: https://helpx.adobe.com/in/indesign/kb/preferences-folder-read-only-issue.html
