1. what GPU do you have?
2. are your drivers up to date?

[geoff-m]

1. Nvidia RTX 3080 (10 GB).
2. Yes.

[Codinablack]

Just for clarification, runs fine on my system, which is windows 10 22h2 with radeon 6400

[geoff-m]

Very clear, I'll be right over to use it!

[joeyballentine]

Do any other electron based apps work on your computer? Such as discord or slack?

[geoff-m]

Yes, both of those do.

[joeyballentine]

@scrawfor that issue is unrelated to your GPU. It looks like some dependencies failed to install. Since that's a portable build, my recommendation would be to delete the python folder at chaiNNer's root and then start chaiNNer up again. Let me know if that continues to happen

[scrawfor]

Ah, you're right. Just looked at his title and assumed it was the same issue. Missed his log. Reinstalling worked.

Sorry for the spam. I'll delete my message since it's irrelevant.

[joeyballentine]

All good, glad it's working now

I found this Electron issue where someone commented:

error_code=18 is SBOX_ERROR_CREATE_PROCESS and means that CreateProcess itself failed, so yeah it'd be expected that we don't see any crash dump data from the gpu process - it never started at all. Error 18 can be caused by running an Electron app from some kinds of non-local / mapped network drive. For example, if you try to run an Electron Windows app inside Parallels from a drive mapped to your Mac, you will get this error.

Looking at your log: Integrated Python not found at S:\chaiNNer-win32-x64-0.22.0-portable\python\python\python.exe (note the S:\) this seems to be the issue.

@geoff-m Try moving your portable installation to another drive.
