We have released InDesign CC2019.0.2 with lot of stability fixes. If you are not on 188.8.131.524 then I would recommend you to upgrade to latest version as it is more robust.
If you still face this issue even after updating, please send the following information to firstname.lastname@example.org :
• Error snapshot or video recording of the issue?
• Is(Are) the issue related to a specific document(s)/asset(s)? If Yes, Can you please provide the document(s)/asset(s)? Please package the entire document(To package the document, Go to File → Package)
• Does Trashing preference and cache, please create a backup of Preference and cache before trashing them, help to resolve the issue?
