In my case I tried many things but nothing works out. My project was old enough and minimum iOS version was also deprecated. Then I updated my project to Minimum iOS supported version '15.6' on XCode and also in 'Podfile' which is the main cause of this issue. And my all pods finally updated to latest.

In Podfile e.g:

platform :ios, '15.6'

Note: 15.6 works for my case. Always check Minimum iOS supported version.
