ExceptionInInitializerError on release compilation, not in debug

[NoeTeria]

Hi,

I have an error when i'm compiling an Android project (Gradle 8.7) that uses HTMLUnit. I have to use “minifyEnabled false” otherwise I can't compile the project.

I get the following error:
Missing classes detected while running R8. Please add the missing classes or apply additional keep rules that are generated in C:\Users\Max\AndroidStudioProjects\HtmlUnitTest\app\build\outputs\mapping\release\missing_rules.txt.

When I add the lines present in the missing_rules.txt file to the proguard-rules.pro file, compilation works, but when the application is launched, it crashes with the following error, only in release version, in debug it works perfectly:

Do you have any idea how to solve this problem ?
Thank you

What OS are you running on your development machine? Grasping, but sometimes extra-long paths can mess things up.

Thanks for the answer, I'm using Windows 11. I don't think the problem comes from the paths, they are not extremely long.
