Discord crashes randomly and kills my polybar, sxhkd, forcing me to hard restart using PC power button (programming.dev)

Hello everyone, I've had an issue with discord on Arch Linux for a long time, but only now had the time to document the error (had to photograph it with phone and transcribe it).

Its a weird one, buckle up.

At random times, discord crashes which causes my polybar to crash, as well as my sxhkd, which obviously means my computer is practically useless until I hard shutdown using the power button on my case. Whats weird is that sometimes it will go weeks without crashing, and other times it will crash frequently in a short time span (e.g. it crashed a couple times yesterday, and once today).

Here is the error as I photographed it:

And here it is after I manually copied it into a text editor (keep in mind I might have missed a character here or there because of this).

A JavaScript Error occurred in the main process

Uncaught exception:
Error: EROFS: read-only file system, write
	at writeSync (node:fs:923:3)

	at Logger.processMessage (/opt/discord/resources/app.asar/node_modules/electron-log/src/core/Logger.js:175:11)

Anyone have any idea how I can troubleshoot this?

I also tried checking the following directory but it doesn't exist on my PC:

/opt/discord/resources/app.asar/node_modules/electron-log/src/core/

I only have the file /opt/discord/resources/app.asar So obviously something is going on there that shouldn't be happening.

I've got no idea how to troubleshoot node apps, so would appreciate any help from those of you who have those skills.

Thanks in advance! Please let me know if you need more info or need me to run commands and show you the output, and Ill do so.

Read only filesystem is the problem, but we need more info to figure out what that means.

Run ls -lh /opt and ls -lh /opt/discord and post the output of both here.

Would also be good to check your drive for SMART errors in case it's on its way out.

As for the drive, my root partition is on an NVME drive which should be fine considering its not even 3 years old.

What info does this give you? As someone more experienced, what jumps out at you when looking at this (trying to improve my knowledge while troubleshooting - 2 for the price of 1 xD)

Okay, well there's your problem. Everything is owned by root, and you're running this program as your local user.

Basically, it's trying to download an update but can't write to the directory because you don't have permissions.

Just install the Flatpak, honestly, and skip this mess.

Digging deeper, I think this is just a bad call one two fronts: the package maintainers, and the Discord devs who should have this as a handled exception instead of bailing like this.

If you want to fix it temporarily, just chown -R [your_username] /opt/discord and that should stop it. I guarantee it'll break on the next pacman update again though.
