PathAccessException: The process cannot access the file because it is being used by another process (Windows only) after breaking changes 9.0.0 #634

After I updated to version 9.0.0, I randomly got an error saying: 'The process cannot access the file because it is being used by another process.'

This only happened after I upgraded to version 9.0.0.

I investigated the issue and came to the conclusion that it comes down to this.

If a file wants to read the same key at the same time as another file is writing to the same key, then I get this error.

I fixed this by switching back to the previous stable version.

I suggest updating the readme to alert users of this breaking issue.

This error also corrupts the .dat file, so all your secure storage is corrupted and unusable.

The error:

flutter: Failed to decrypt data: Error 0x00000057: Failure on CryptUnprotectData()
Delete corrupt file: c:\users\USER\appdata\roaming\com.example\APPNAME\flutter_secure_storage.dat
