Description

Buildx crashes when trying to set driver opts. The corruption prevents DD from starting.

colin@MacBook-Pro  ~/Developer/docker/build-bench  docker buildx create --name do-nyc-1 \                                                                                            SIGINT(2) ↵  695  12:04:14

Expected behaviour

Builder node to be created with correct settings and no crash

Actual behaviour

Buildx crash and DD fails to start. The only fix is to go in and remove the instance

rm ~/.docker/buildx/instances/do-nyc-1
