The thing is - I know you are changing the Paragraph Style - but the crash is probably not related to that style at all.

I'd start by creating a new document with same page size and margins etc.
and have the old doc open.

In the old doc - go to the pages panel sub menu - and then choose Move Pages - with all the pages selected your old document you can set the target to the New Document

This will insert all your pages to the new document - and in essence rebuild it. 

See if it crashes here.

If it does - you have a test document to work with now.
So you can start deleteing half the content - see if it crashes 

If it still crashes - then delete more content - see if it crashes
then keep halving the document content to see what is crashing it

it doens't take long to track down the page/content that is crashing

--------------

On another note - it might not be that

Here are some presaved thoughts on fixing crashes in order of which to try 

----

If a document is not behaving well then try 

File>Export 

Choose IDML

Open the IDML in InDesign
Save the file as a new InDesign file with a new name
See if the issue persists.

---

Try resetting your preferences:

Windows: Start InDesign, and then press Shift+Ctrl+Alt. Click Yes when asked if you want to delete preference files.
macOS: While pressing Shift+Option+Command+Control, start InDesign. Click Yes when asked if you want to delete preference files.
A dialog will appear asking to delete the InDesign Preferences, select 'Yes' on this dialog.

Reinstalling rarely fixes everything - you can do a complete reinstall using the
Creative Cloud Cleaner Tool https://helpx.adobe.com/creative-cloud/kb/cc-cleaner-tool-installation-problems.html

First, try to update to the latest version - InDesign 19.3 - and see if it makes a difference. If not, let us know your operating system version. Also, try to export the doc as IDML then open IDML and see if it solves the problem.
