Hello. I’m using a Spyder 5 Express calibrator wtih DisplayCal 3.9.16 on Windows 11 Home 24H2 release. I have an Nvidia graphics card with driver ver 576.02. I calibrated everything fine and it worked for about a week or so. I don’t leave the calibration device attached to the PC. I just used it once during calibration and then disconnected.
Occasionally, after I start the PC I’ll get DisplayCal errors pop up. Specifically one that starts with ‘C++ assertions “”Assert Failure”” failed at…… ‘ I attached the 3 screenshot of the full error. Does anyone have any suggestions on a possible fix? A few weeks ago I got the same issue, but then decided to reinstall the program and it worked fine for a bit until today. I do have the windows display ‘Scaling’ set to 175%, if that makes any difference?

Thats where I got it from, github. The latest version.
2025-06-03 at 19:10 #143576My best is I do not know reason. If it is displaycal py3 version problem please report it to github. I have not switched to the py3 version. It could be a C++ error or a system error. Not enough info to check the windows system. Do the sfc /scan now and dism checkup. https://support.microsoft.com/en-us/topic/use-the-system-file-checker-tool-to-repair-missing-or-corrupted-system-files-79aa86cb-ca52-166a-92a3-966e85d4094e . Reinstall the C++ distributables. I think I am wrong about it being C++. It must be python. Python asserted the error. Python probably updated and only certain version of python work in py3 version.
