That's a bummer.
Code:
[I] JEB 5.38.0.202603112011 (Super-Black Edition by CXV) ...
[I] System: Windows 11 10.0 (amd64) en_US
[I] Java: Oracle Corporation 22.0.2
Tried win 10 x64, win 11 x64.
Each with jdk-21.0.10, jdk-22.0.2 and jdk-23.0.2.
Jeb extracted straight from the zip both as is and with jvmopt.txt.TEMPLATE renamed to jvmopt.txt.
With and without internet.
All options by default. On a couple of questions like load all assets or run additional apk unpacking answer is NO. Just load apk, save project, close jeb, rerun and open saved project.
And in all of these cases it still fails to load saved project exactly the same way.
