Answer 1

You can understand what is happening by reading the error log
EPERM: operation not permitted, mkdir 'C:\Program Files\nodejs\node_modules\.npm-QXjMEw5N'
EPERM is the code for the permission issue. Here, you cannot create (mkdir) a new directory called .npm-QXjMEw5N inside C:\Program Files\nodejs\node_modules\ because you don't have the permission to do that.
Macro: int EPERM “Operation not permitted.”
Only the owner of the file
(or other resource) or processes with special privileges can perform
the operation.
You can try running the command line as administrator to have the appropriate privilege, then rerun npm install -g nodemon

Try to clear your cache then install again? Something like npm cache clear --force then npm i
