Getting “com_error: (-2147221005, 'Invalid class string', None, None)” from the method dispatch(Excel.Application) from pywin32 in python

I am getting the below error while running the given code from Azure devops pipeline and the same code works fine when triggered from local virtual machine. Any help would be indeed appreciated!!!
