@ferenj-gs thanks for reporting this issue

is this issue reproducible?

from log it seems the thread_name of BambuStudio is wrong in your environment it cause the context check failed

and what does this mean "Create App profile under windows Graphics settings for bambu studio to use the dedicated T550 GPU"

[CrashTestCoder]

I reproduced this issue. same thread name, same error. I went into settings and told windows to make bambu studio use my T600 nVidia GPU.

is this issue reproducible?

@CrashTestCoder

is this issue 100% reproducible?

[CrashTestCoder]

Will verify when I get back to my computer in the morning. But it persisted through reinstalling the software and multiple reboots.

Disabling the manual gpu selection fixed it immediately

[CrashTestCoder]

I just tested on my old personal laptop and it is not reproducible with a Nvidia 940mx. So maybe its just a problem with quadros? Will report back in the morning

[CrashTestCoder]

Can confirm. 100% reproducible.
