AWS Toolkit fails with FileAlreadyExistsException

[headsphere]

I get the error below whenever I launch Rider. Also no profiles appear in the AWS toolkit dropdown box for me to select, despite the .aws credentials file being correctly populated.

java.util.concurrent.ExecutionException: java.nio.file.FileAlreadyExistsException: C:\Windows\TEMP\1\service-endpoints.json-9c185833-ad4d-45a7-9370-96d2992ff76f13157487549953523421.tmp -> C:\Users\trpkc39\AppData\Local\JetBrains\Rider2025.1\aws-static-resources\service-endpoints.json
