flutter fvm error when using `use` command to change flutter version

Question

I'm trying to use flutter fvm version management but I'm getting this error when I try to use new version. Will that config be created automatically? And how to enable permission?

D:\dev_projects\myapp>fvm list
Cache Directory:  C:\Users\user\fvm\versions

2.2.3
1.22.5 (active)

For me it was because I copied a flutter project folder. I deleted the .fvm folder and did fvm use and it worked

I fixed this issue by turning on developer mode as the logs suggest. Go to your Settings, search for Developer settings and enable it from there. Now restart the IDE and try again.

I don't know if this is the correct way but I solved it by running vscode as administrator.
