Steps to Reproduce:

1. Im using this devcontainer https://github.com/nextcloud/server/tree/master/.devcontainer
2. With a different devcontainer.json

{
	"name": "NextcloudServer",
	"dockerComposeFile": "docker-compose.yml",
	"service": "nextclouddev",
	"postCreateCommand": ".devcontainer/setup.sh",
	"postStartCommand": ".devcontainer/postStart.sh",
	"forwardPorts": [
		80,
		443,
		8080,
		8025
	],
	"customizations": {
		"vscode": {
			"extensions": [
				"bmewburn.vscode-intelephense-client",
				"ms-azuretools.vscode-docker",
				"xdebug.php-debug",
				"donjayamanne.githistory"
			],
			"settings": {
				"php.suggest.basic": false
			}
		}
	},
	"workspaceFolder": "/var/www/html",
	"remoteUser": "devcontainer"
}

Does this issue occur when you try this locally?: Yes
Does this issue occur when you try this locally and all extensions are disabled?: Both

check #9943

Window is stuck at this state

and not responding anymore

To get it working again you need to clean the database as indicated in the following comment https://github.com/microsoft/vscode-remote-release/issues/9943#issuecomment-2322255981

This happens due to port forwarding, currently i have this ports in my json:

        "dockerComposeFile": "docker-compose.yml",
	"forwardPorts": [
		80,
		443,
		8080,
		8025
	],

and this ports in my docker compose

    ports:
      - 80:80
      - 443:443
      - 8080:8080
      - 8025:8025

Rows in database:
SELECT * FROM ItemTable WHERE key LIKE 'remote.tunnels.toRestore%';
