Archived discussion. This page is a verbatim copy of a thread from
community.ansel.photos, the Ansel community forum, which ran from March 2023
until it was taken offline in June 2025 after the site was compromised — a counterfeit
site had been planted inside the forum software, so the whole thing had to come down.
The original address was https://community.ansel.photos/view-discussion/ansel-crashes-during-start.
No crawler ever captured this particular thread, so the text below — taken straight from the forum database — is the only copy left.
Answers may refer to older versions of Ansel, and image attachments did not survive the shutdown. Current discussion happens on GitHub Discussions .

After installation of Ansel on my Windows 11 laptop, when I start the program, it crashes after a minute or so : no UI appears at all.
I join here the trace file generated by Ansel. I think the problem is dealing with OpenCL functions…
Note : The driver for my GPU (Intel IRIS Xe) is the latest one available (31.0.101).

You have an OpenCL error here, probably linked to a rotten OpenCL/GPU driver. Try to update/downgrade that driver or remove it entirely. Alternatively, you can try to start Ansel in command line with --disable-opencl.
Note that running the latest driver is not always the best idea, if you use experimental branches. Try to stick to the stable/production drivers, which are never the latest.
