I had the same issue and just downgraded docker back to 28.5.2 and it instantly fixed the issue.

Here are the steps if you need them for ubuntu:

1. Stop Docker

sudo systemctl stop docker

2. Install the specific Docker version

sudo apt install docker-ce=5:28.5.2-1~ubuntu.24.04~noble \
                 docker-ce-cli=5:28.5.2-1~ubuntu.24.04~noble \
                 containerd.io

3. Prevent Ubuntu from automatically upgrading Docker:

sudo apt-mark hold docker-ce docker-ce-cli

4. Start Docker again

sudo systemctl start docker
sudo systemctl enable docker

5. Verify the version

docker --version

You should see:

Docker version 28.5.2, build …

Once this issue has been fixed you can run the following to update docker back

sudo apt-mark unhold docker-ce docker-ce-cli


For PiOS:

sudo apt install -y docker-ce=5:28.3.2-1~debian.13~trixie docker-ce-cli=5:28.3.2-1~debian.13~trixie containerd.io
