Selecting the Reapply option for a VM that failed to start will not cause data loss. The Reapply action is designed to reapply the VM's state, which is useful if the VM is in a non-startable state due to a configuration issue. However, it's always a good practice to have backups of your data to prevent any accidental loss in case of other issue that you might encounter
If the VM is stuck in a failed state, try reapplying your VM's state before redeploying.
