startup and other crashes solved by disabling nahimic service

Sat Oct 24, 2020 2:23 pm

- some weird crashes during work
- 100% crash during startup if trying to start on non-primary monitor
- some other visual glitches

All this I tried to debug for a while, found some of the GL functions that fail and got a solution from s3d guy's in a way of disabling native GL and moving to angle by setting env variable QT_OPENGL=angle. It became obvious this is not S3D only issue as same problem I had with PrusaSlicer and IdeaMaker too (they don't support angle so that hint did not help for them)

finally I found the actual reason for the problem and a real solution that solved everything

problem is nahimic service that is a POS that just don't work that installs with realtec sound driver... disabling the service solved all my issues with s3d (and a bunch of issues with prusa slicer, ideamaker, dxo photolab, davinci resolve ...)

In my case, I haven't got this service, but Simplify3D crashes continuously without a reason. Usually it crashes when I edit a profile and update it. It's driving me crazy

Any chance you're using special characters/umlauts somewhere (gcode comments, process name or so?)

There's few threads about this, like this one here: viewtopic.php?f=9&t=13790

I had this problem, started with 4.0. The issue is a corrupted profile. Something somewhere is corrupted. I tried everything, talked to support... and the only thing that solved the crashes
1. backup all your profiles one by one, not as factory file as it is unreadable but export profiles as FFF files, one by one
2. uninstall s3d and delete EVERYTHING wrt s3d
- delete Computer\HKEY_CURRENT_USER\SOFTWARE\Simplify3D registry tree
- delete C:\Users\<username>\AppData\Local\Simplify3D and everything under it
3. run some registry cleaner (CCLEANER free version is enough), reboot
4. install s3d
5. create all profiles MANUALLY!!!!! - DO NOT IMPORT the exported fff files, create profiles from scratch manually, open the stored FFF files in text editor or some xml editor, all the parameters are human readable in the xml files...

now it should work ok.

if you restore FFF files back in you might again have issues with crashing... I think one of the release, 3.x or 4.0 had a bug that corrupted one of the profiles, the only way to get out of it was doing this procedure..
