Hi @Dhana Harsha Polisetty (Contractor)

Welcome to Q&A.

I want to help you, but according to your description, this issue focuses more on Office add-in development, we deal with Office general issues.

The tag for this your thread should be "Office Development", so I will add it. Thanks for your understanding.

I find following steps via searching online, you may have a look:

1. Close Office.
2. Check that the time and date are set correctly on your computer. An incorrect time and date can cause issues when verifying the add-in's manifest.
3. Verify that the manifest is valid. See Validate an Office Add-in's manifest.
4. Restart the add-in.
5. Install the add-in again.

For more, please refer to the link: When installing an add-in, you see "Error loading add-ins" in the status bar.

Besides, if you want other Office developer resources, please check out this link: https://developer.microsoft.com/en-us/office#officecommunity:~:text=Office%20developer%20resources

Hope the information could be helpful.
