[CLOSED] Every time I use a style in a specific manner LO stop working

My PC details are:
CPU Intel Core i5-6500
RAM-4 GB
OS-Windows 10 x64

Currently, using LibreOffice 6.4.4.2 (x84)

While making a document a copy a piece of text that is supposed to be a title, so after I copied it, I go to writer, I put the mouse at a blank line, then FIRST apply a personalized style (using a template created by me) AND THEN paste the text to that line with a style, immediately or after I press enter for starting a new paragraph the program crashes.

Now there is a catch, if I FIRST paste the text, then select it and SECONDLY apply my personalized style nothing happens, and the program continues running smoothly. I already run it in secure mode and the problem persists. I have also disabled all the extensions but that doesn’t solve the problem

Why is this problem? How can I solve it?

Please file a bug report. Attach a sample file with the style, and give specific steps to reproduce, like “select sentence 3 using triple-click and Ctrl+C; put cursor to the end using Ctrl+End; press F11 and double-click MyStyle under paragraph styles; press Ctrl+V; press Enter”. Please do that even if you believe that “any file or sentence will do”, because if it’s so, then specific steps and sample document won’t hurt, but they would allow to be sure that others do exactly what is known to crash on your system.

By the way: have you tried to reset your profile?

Never mind, I tried to reproduce it in several ways but with no success. Last night it was very difficult trying to use writer without crashing but the program now just works flawlessly
