Question

I recently downloaded flutter and other related apps to my pc.I am however unable to run flutter doctor on the terminal.I am also unable to create a new flutter project on android studoi. Each time I try to do any of the above, I get the error

C:\WINDOWS\system32>flutter doctor
Cannot open file, path = 'pubspec.lock' (OS Error: The parameter is incorrect.
, errno = 87)
Running "flutter pub get" in flutter_tools...
pub get failed (66; , errno = 87))

C:\Windows\System32>

I have tried updating the path in my environment variables but that failed. Please help.
