darktable 5.4 - color calibration problem, crashes in various situations

Is there an existing issue for this?

• I checked and did not find my issue in the already reported ones

Describe the bug

Context:

1. Darktable 2.21 works fine in Windows 10.
2. Upgrade to Windows 11
3. Darktable 2.21 opened without crash. No photo editing done.
4. Upgrade to darktable 5.4.
5. Problem: color calibration of some files. Not all images have problems with color calibration.
6. Darktable 5.4 crashes, when attempts at editing photos are made.
7. Darktable 5.4 uninstalled, darktable 5.21 installed again. Problems with color calibration remain. The previous version crashes.
   Attempts to solve the problem lead inevitably to crashes.
   Similar problem has been submitted, but I believer I provide additional contexts for the crashes.

Please provide additional context if applicable. You can attach files too, but might need to rename to .txt or .zip

Additional context provided in zipped files.

Start by reviewing darktable-log_29_01_2026.txt and darktable_problem_event_viewer_29_01_2026.evtx in the attached zip. Compare the reported crashes during library import, lighttable scrolling, color calibration, and darkroom editing on Windows 11 to identify one reproducible trigger. Done means one crash path is isolated and the expected no-crash behavior is verified.
