2.5.0 error on startup I receive "Unhandled unknown exception; terminating the application"

[MiFixIt87]

Description of the bug

At startup I receive the following error

when I click OK to that I receive the following:

I have searched for information on this error and one thread indicated that it was related to an NVIDIA graphics setting. I checked my NVIDIA settings and mine are correct.

My system is:

Prusa Slicer 2.5.0+Win Dell Precision 7760 Intel UHD Graphics (only using the built-in display) NVIDIA RTX A6000 graphics (No external displays connected) 32GB RAM 1TB NVMe SSD

I had this same issue with Prusa Slicer 2.4.0 and upgraded to 2.5.0 hoping it would cure the issue. It never proceeds to a point where I can export the configuration or configure printers.

Any ideas?

Project file & How to reproduce

Start Prusa Slicer or try to 3d print from Fusion 360 with Prusa Slicer set as the application to print to.

Hi, there is quite similar issue #9178.

[MiFixIt87]

I saw that before I posted and I tried the solution that worked for the OP ( see the NVIDIA setting screenshot in my post) and it did not resolve my issue.

[MiFixIt87]

Closed accidentally, issue is not resolved.

I'm having the same issue with PrusaSlicer 2.5.0 and my Nvidia settings are to allow the application to decide.

I did have an unexpected Windows shutdown earlier that I suspect is the trigger. PrusaSlicer 2.5.0 has been working fine for weeks before the event today.

My PrusaSlicer.ini file does not look corrupted - I didn't try to manually compare the MD5 but there is no garbage in the ini file. Also the .ini.bak file matches the main .ini file. There are 7 other ini files in my PrusaSlicer roaming profile and none of them have any garbage / apparent corruption.

I also tried removing my .ini and .ini.bak file temporarily and that made no difference. I've also tried repairing my installation which didn't help. I've tried other NVIDIA settings which had no impact. I booted my system with 3rd party services disabled and that had no impact. I don't see anything in the Windows Event Viewer logs but not certain what events I might look for.

---

Interestingly, if I run prusa-slicer-console.exe --sw-renderer, the error does not happen

This may be a workaround for me in the coming days - not yet sure. I have to see if all the functionality still works.

I ran prusa-slicer-console .exe normally (i.e. not using sw rendering) with loglevel 5 and got the following output

My system is an HP Laptop - ZBook Firefly with Windows 10.

I'd be happy to run a diagnostic build if that helps.

The normal PrusaSlicer.exe also accepts the parameter --sw-renderer. For now, I've just created a shortcut and all is working fine. Of course would love to get back to normal rendering at some point, but for the desperate:

[MiFixIt87]

I tried your workaround for my issue, and it works on my system as well. If you do find a solution that allows for hardware graphics, please post it here or DM me if possible. Thank you very much!!!!!

[Tux0Topo]

Also having the same issue. Notebook, with Windows 11, intel i7 11th gen + RTX 3080. --sw-renderer is a bypass. Any one knows if the lack of HW renderer will be that bad?

Its been fine for me. Not saying I like the idea but performance-wise I don't notice a difference for what I'm doing.

[kubispe1]

Have you tried also 2.6.0? alfa 2? Please? Can you check ?

[Tux0Topo]

Same error with Versión 2.6.0-alpha2+win64.

[Tux0Topo]

alpha3 also having the same problem!

[jrwaters2]

Of course - will definitely let you know. Been experimenting with driver upgrades. So far no luck.

Can confirm this issue on Dell 3571, Windows 11 Pro (10.0.22621 Build 22621) and NVIDIA T600 driver 517.66 for prusaslicer 2.5.0 and alpha3.

Dell pushed driver updates for video in january. Maybe those are of help. NVIDIA Txx0/Txx00/RTX Ax00/RTX Ax000/GeForce MXx50 Graphics Driver - A04 Intel UHD/Iris Xe Graphics Driver and Intel Graphics Command Center Application - A09

--sw-rendered does help

[bubnikv]

Hopefully fixed with 84722876012ca310e29b291e10fef9d18ae26cea Implementing a test whether the current thread is the main (UI) thread and using it on AppConfig::save() to assert if save is called from a worker thread. The old assert was using thread names, which did not always work on Windows.

I have the same error with PrusaSlicer-2.6.0-alpha3+win64-202302031521_signed on Dell Precision 5570 Windows 11 10.0.22621 N/A Build 22621 Nvidia RTX A1000 Driver version: 31.0.15.1766 12th gen Intel i7-12800H NVMe PC801 32GB ram

[lukasmatena]

@MichalBuzek That is expected. @bubnikv's fix was done after alpha3, so the first version to test the fix will be 2.6.0-alpha4.

[Renbrant]

--sw-renderer

This resource did not work for me.

[Tux0Topo]

ITS FIXED ON ALPHA 4!!! Great!!! Thanks!!

[lukasmatena]

@Tux0Topo Thanks for the update. Closing.
