Hi again Sunil -
Are you running the Realtek driver from MSI downloads here:
https://www.msi.com/Laptop/support/GV62-8RE#dow... ?
The reason I ask is that you can get in trouble using driver updaters which no expert recommends. Because the manufacturer for a gaming rig like yours usually modifies the drivers you want to stick with their drivers unless otherwise indicated.
So compare the chipset, display, audio, BIOS and all other downloads available on that page with what you presently have installed in Device Manager and change them out if necessary.
Also, how soon after the 1903 update did this crashing start? Did you try rolling back as shown in the steps I gave earlier? If this was caused by a Version Update then for 10 days you can roll it back in Settings>Update & Security>Recovery and then hide it until it matures using the Hide Updates Tool which is explained more here:

After 10 days you can reinstall the older version using downloads available from Microsoft TechBench here: https://tb.rg-adguard.net/public.php
Burn to DVD using WIndows Image Burner or create bootable flash using one of the options here: https://www.tenforums.com/tutorials/2376-create...
