The README.md says to use opencv-platform. If you're not using that, then don't expect things to work. What more do you need to know?
What you mean is that instead of doing this:
<dependency>
<groupId>org.bytedeco</groupId>
<artifactId>opencv</artifactId>
<version>4.9.0-1.5.10</version>
<scope>compile</scope>
<classifier>windows-x86_64</classifier>
</dependency>I'm supposed to do this?
<dependency>
<groupId>org.bytedeco</groupId>
<artifactId>opencv-platform</artifactId>
<version>4.9.0-1.5.10</version>
<scope>compile</scope>
<classifier>windows-x86_64</classifier>
</dependency>from javacpp-presets.

Please try again with 1.5.10
from javacpp-presets.

Just tried it with 1.5.10, the issue is still there.
As I said, it's not consistent and happens only on some Windows 11 machines, no idea why.
What can I do to investigate it further?

Please set the "org.bytedeco.javacpp.logger.debug" system property to "true" to get more information on the console.

OK, here are the results, I think the issue is pretty clear (missing OpenCV dependencies):

I checked the opencv_core.dll file in DependenciesGui and got this:
For opencv_imgproc.dll those are missing:
No idea why was it linked against those VS libs?

Those are available with javacpp-platform

It looks like the issue is easily fixable (I mean not fixable, but it's relatively easy workaround) by installing this:
https://learn.microsoft.com/en-US/cpp/windows/latest-supported-vc-redist?view=msvc-170#latest-microsoft-visual-c-redistributable-version
from javacpp-presets.

I don't understand. Is there another dependency I need to list in my pom.xml? I would really appreciate if you replied with a more elaborate explanation from time to time :)

I assumed that fixed it, but please let me know if that still doesn't work
