A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Hello Sudhir V,
Thank you for contacting the Microsoft Support community.
Issue is similar to the one in the below link

What it says that, the error means there is some corruption in the system files causing the office not to activate.
Although the solution says reinstall, I will ask you to do an office online repair. Since you are using a more current OS and Office (presumably).
The steps for an online repair is as follows:
- Right Click on Start > Select Apps and Features
- Scroll down until you see Microsoft 365 Apps
- Click the three buttons beside the Microsoft 365 Apps
- Select Modify
- Click Online Repair (this will take a while to be done)
