I'm very sorry to say that, but you are working with a very outdated environment and all your tools and libraries are years behind and unsupported by their respective maintainers at this point.
You are using the caret (^) version for Apollo Client, so ^3.5.10 includes every 3.x version higher than that - it doesn't really tell us which version of Apollo Client you currently have installed. It could even be the current 3.8.6 version.
There is a good chance that some part of your build environment is not able to parse a newer release of Apollo Client as there might e.g. newer TypeScript syntax in there that might not be supported by the TypeScript version you have installed. Your best chance is probably to slowly increase your other tooling versions until it works again.
          
Thanks for the quick reply.

For now temporary fix I applied is to use "@apollo/client": "3.5.10" (removed ^)

But we will definitely have to upgrade to the latest version of the library.

Thanks again.
          
Just keep in mind that doing this could also mean that you e.g. accidentally downgraded from 3.7.12 to 3.5.10 - you don't know which version you really were on.

I'd recommend that you look at the git history of your package-lock.json to find that out.
