Why we can't have a printable pdf , when helpndoc that you use for the webhelp have print etc.
Or why we have to stop been productive whille we work inside a dcc application , lose focus and go online for web help to check for a funcion, not to mention that all dcc plugins hardly get updated ...

Solution ,
dunno why, it was my startup.blend that i use from 5.0 version.
deleted c:\Users\dinos\AppData\Roaming\Blender Foundation\Blender\5.1\config\startup.blend
started blender / enabled all addons / saved startup and fixed, now I can enable disable octane, and with all addons I had loaded ...

Disregard , I made a backup of my local roaming and uninstalled blender.
So i started with no previus local profile , Installed blender again and added just octane. (profile started as new)
It works, so i will try to figure out what was wrong in my backup profile I had kept as backup, if found smth ...

Lino I disabled all , deleted the octane from scripts , reinstalled it and had only octane active.
restarted blender with opengl, tried to diable octane , crashed.

I just after seeing this I send you the log with all plugins,
If you want i can clear the crash log and send you the generated crash ...

Changed to openGL , but have the same crashes, you might need to check it.

Oh changed to Vulcan just when I installed 5.1.1 to see the faster compilation to viewport and I might forget it there.
Will check

Thank you

Oo you got me!

Thanks

Blender 5.1.1 with octane 31.6.0

It does that crash even with all other addons disabled.

crashlog attached

Thank you

If you go in preferences and unload the plugin blender 5.1 crashes, that with 36.1

I noticed as i use an addon to load unload plugins.

Thank you

Done everything i described, not working for me...
Take a look ?
