Hi Anand Sri

Thank you for your instruction how to fix: fatal error…

It worked.

One other issue with Adobe Acrobat Reader DC. Rev: 18.009.20044

I am a lot on metered connections.  Updates can and do require a lot of large data to be downloaded.  Not desired on metered connections.

How can I disable Auto Update for your product?

Current OS:  Windows 10 and Office 365

I look forward to hear back from you.

The updates in Adobe Reader DC is set up for continuous updating. You can modify those settings via Adobe Customization Wizard DC or with the Windows Registry.
