"Process is not defined" & "Export from package.json"

[byrmylmz]

Hello,
I have two problems.
The first one is about the export of the version from the package.json file. I have update these lines in indoor.js but compiler don't recognize my correction on code.
The second one is "Process is not defined." I have tried all solutions suggested on Stackflow and couldn't solve that problem.
The only solution is downgrading the version of react-script "4.0.1", but this has triggered another problem with other packages.
Do you have any suggestions for working with the latest version of react script "5.0.1"?
Thank you in advance.
