Prusa-slicer has stopped working. Don't know why or how to fix it.

My prusa-slicer no longer loads.  I get the following error before it crashes:

[2026-01-12 09:15:31.607028] [0x00007f95d27fb940] [error]   UserAccount: Failed to read token - no datafile found.

Segmentation fault         (core dumped) prusa-slicer test.stl

Prusa slicer appears on the screen (only a portion), and then crashes.  I have been doing regular updates, but no idea which one might have broken it.

How can I get prusa slicer to start working again?

$ uname -a
Linux cholo 6.18.4-arch1-1 #1 SMP PREEMPT_DYNAMIC Fri, 09 Jan 2026 19:43:48 +0000 x86_64 GNU/Linux

EDIT: It definitely broke over the last 2 updates, because I remember using prusa-slicer 2 days ago without a problem.

Might be the same problem, but to my knowledge I'm not running wayland.

It's weird, I can run KiCad without any errors.  But prusa-slicer still won't load.  So maybe it isn't the same?

Sounds a bit like the issue reported here: https://gitlab.archlinux.org/archlinux/ … /issues/12

I'm not understanding how to fix this, or even if it is possible.  But I need prusa-slicer to work, as I am missing production time.

Can someone offer a possible suggestion please?

So if I roll it back, does this stop me from getting nightly updates?  And if so, how long should I wait before trying to update to current?

@NeoGeo yes, don't update again until that bug report linked above is fixed.

But for me, I attempted rolling back to 2025/12/13 and got

error: failed to prepare transaction (could not satisfy dependencies)
:: installing alsa-lib (1.2.14-2) breaks dependency 'alsa-lib=1.2.15.2' required by lib32-alsa-lib
:: installing glew (2.2.0-7) breaks dependency 'glew>=2.3.0' required by lib32-glew

Having the same GLX errors with prusa-slicer on Sway/Wayland here.

This is quite nasty, I had to downgrade glew and a lot of python stuff to get to work the also downgraded versions of Prusa Slicer, KiCad and FreeCad. Hope this gets fixed soon, as I expect some more stuff to fail because of the python downgrades.

I can run KiCad and FreeCAD without problems.  Only prusa-slicer seems to be failing for me.  My current work around is to just use the command line to slice my files, but it is very limited in what you can achieve.

Hope this gets fixed soon!
