Issue
I am running into the following error when starting up containers on my Raspberry Pi 3B on Raspbian Buster:
docker: Error response from daemon: : signal: illegal instruction (core dumped): unknown.
ERRO[0001] error waiting for container: context canceled
Lately I've been maxing out resources on the Raspberry Pi 3B (looking into upgrading but I don't want to stop selfhosting in the meantime), so sometimes containers are exiting error status due to lack of resources.
Containers have been working fine when restarting until this morning. This morning I've been getting the above illegal instruction error. This happens with all containers I have, docker and docker-compose, and even just when running docker run hello-world using dockers hello-world example container. There hasn't been any updates run in a week, so new updates likely wouldn't be the problem (namely with docker-ce, raspberrypi-kernal which have cause conflicts in the past but were quickly resolved).
I've tried rebooting, removing and installing docker-ce, removing all containers, removing all networks, removing images, and restarting the Docker Service.
When running something like docker-compose --verbose up -d lidarr, the illegal instruction error always seems to occur around connecting to the network. Towards the end of the output is below, with some of the repetition removed:

Containers, to name a few, that are "causing" the illegal instruction error:
- FireFlyiii (fireflyiii/core:latest, image ID 1da032b42837 from 2 weeks ago)
- MariaDB (yobasystems/apline-mariadb:10.4.15, image ID 52efb22cde7e from 16 weeks ago)
- Lidarr (linuxserver/lidarr:latest, image ID b21ad10fe43c from 12 days ago)
- hello-world (hello-world:latest, image ID 1ec996c686eb from 4 months ago)
Update: I checked Journalctl for docker entries after trying to docker run hello-world and found:
Feb 26 13:08:25 raspberrypi dockerd[4602]: time="2022-02-26T13:08:25.253390090-05:00" level=error msg="stream copy error: reading from a closed fifo"

Does anyone know how to diagnose and/or recover from this?
Solution
I was able to resolve this, unfortunately I won't be able to find out why this happened.
I tried removing and installing docker-ce and dependencies again. I wasn't able to remove due to containerd.service not stopping. I found it was set to always restart, which would normally make sense. I then ran sudo systemctl disable docker containerd and rebooted. I confirmed those services were no longer running by following journalctl output, looking for the usual restarting and core-dump errors from docker and containerd.
I ran sudo apt remove docker-ce and sudo apt autoremove again, then ran docker's get-docker.sh which reinstalled docker. I then ran sudo systemctl enable docker containerd and sudo systemctl start docker containerd. Docker is the same version it was before and the hello-world container and other containers of mine that wasn't previously running is now running successfully.
