Hi @rngeer,
As long as you have not emptied the trash you should be able to restore a GiveWP form.
Here’s a quick screencast to demonstrate: https://somup.com/cr6ObY3g7O
If that’s not happening on your site, the next step would be to try our Health Check tutorial. This can allow you to test your site with different plugins without hurting the front-end of your site at all. https://givewp.com/documentation/resources/troubleshoot-wordpress-websites-health-check/
Let me know if you find a conflict with another plugin or the theme.
