6.79 won’t work for sure as of today.

How were you managing in the old version with 512M limit?
What is your file size?

I found a solution based on what you guys suggested.
We need to downgrade to a previous version.

How to downgrade?
There are two ways:-
1) Using WP Rollback plugin
2) Manually download the old version of plugin and upload it (Go to www.remarpro.com download page from your browser. Click on Advanced View–> Select your version and download.)

I had issues with version 6.78, so I went with version 6.76. It worked for me.

Hope it helps
