It is not an OpenCL issue.
It seems to load fine until this last line:
2.584292 [camera_control] loaded 4 port drivers.
Do you have a camera connected to the PC? Trata de empezar darktable sin esas conneciones.
No, I don’t have any devices connected to the surface tablet, except for the keyboard and mouse via bluetooth.
On the amd ryzen I only have a mouse connected by usb.
Just wondering, am I correct in assuming that this build has the ‘BUGFIXES new iop cache issues #12393’ fixes in it? I’m new to Github - so this is probably a silly question 
Edit: I mean this latest windows insider build.
I guess it was a silly assumption… I just installed this version and it still crashes, on subsequent exposure adjustments, albeit without giving any errors.
I’ll try next week’s version 
It is not. That PR was merged today and bill did his build last night.
Check to see if the nightly builds run and try that one instead.
Yes, I thought that must be it. Where do I find windows nightly builds? (another questionable question 
)
The nightly PKG will have the windows install file if you log in GitHub.
But the nightly failed to build for the last 3 days.
The nightly builds are failing because of this:
FAILED: lib/darktable/plugins/lighttable/libgamepad.dll
I boot the windows PC and build the current master on UCRT. Installed it without a problem.
SDL2 was updated via this PR: https://github.com/msys2/MINGW-packages/pull/12793
Someone already started an issue in MSYS2: https://github.com/msys2/MINGW-packages/issues/12874
Thanks for all the info. Sounds like I’ll just wait a bit… I keep thinking of learning how to build it myself, but I’ve got too much on at present to concentrate on it. 
The nightly is running again.
Thanks for the update! I’ll try it when I get a chance
Nothing changes on my surface 8 with iris Xe.
After installing, as soon as I run it it shuts down.
I would like this resolved before 4.0.1.
Does it happen to anyone else?
I dont have a Surface system, so I cant test your issues. I’m concern with multiple installs you have. Are you sharing the same .config file across all these? Maybe use .\config_test
Can you provide a -d all from the build from last night?
2.827333 [camera_control] loaded 4 port drivers.
Seems to stop after libgphoto2 init… What are your CAMLIBS and IOLIBS environment variables?
Before launching in the command window, try:
set CAMLIBS=C:\Fotografia\Darktable\DT_41-crash\lib\libgphoto2\2.5.30
set IOLIBS=C:\Fotografia\Darktable\DT_41-crash\lib\libgphoto2_port\0.12.1
.\bin\darktable --disable-opencl --configdir “.\config” -d all
With multiple versions installed/present, these also need to point to the appropriate location for each different version.
Well, I know why it is. I will keep it in mind.
Thank you.
Bueno, pues ya se porqué es. Lo tendré en cuenta.
Gracias.
