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.
