Fwd: prusaslicer-2.9.4p2 segfault

I did a sendbug and Kirill A. Korinsky suggested I send the report to ports and to Renato in CC so here it is.
I will actually add how to better reproduce it, attach my prusa slicer config, the output I get when I try to start prusa slicer and the cor dump (all compressed).

To: <bugs@openbsd.org>


>Synopsis: prusaslicer-2.9.4p2 : UserAccount: Failed to read token -> Segmentation fault
>Category: user
>Environment:
System      : OpenBSD 7.9
Details     : OpenBSD 7.9 (GENERIC.MP) #8: Fri Aug 21 13:32:14 MDT 2026
root@syspatch-79-amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP

Architecture: OpenBSD.amd64
Machine     : amd64
>Description:
  before last path I was actually using pruca slicer nearly normall. itr just required hacking the config from linux because it refused to create a default config. After I ran uptades starting rusa-slicer now gives me segfault complaining about
[0x000008b14b4f3628] [error]   UserAccount: Failed to read token - no datafile found.
>How-To-Repeat:
I am attaching my prusa slicer config, the output I get when I try to start prusa slicer and the core dump (all compressed and I believe as links to my google drive).
the config tarball has full path from home folder so just extract it to the home folder.
make sure you gave the same version I have prusaslicer-2.9.4p2
try to run prusa-slicer
just in case it proves difficult to duplicate I attached also the compressed core dump (they should all be links to my google drive so no big data transfer intrinsic to this email itself)
>Fix:
I have been unable to find any workaround but doing a google search with "[0x00000d7c0a91e210] [error]   UserAccount: Failed to read token - no datafile found.: did find me some hits on what might need to be done while compiling it.
