I am also having the same error. Before it was generating the apk normally, but with this new update it started to have this error.
there was a problem when exporting the project to an application, it always got an error and a view log appeared, someone please help me
The progress bar stopped on 70% with the same error above
I was reading that several extensions no longer work on Android 14
The application works perfectly in companion but it cannot build APK
but a v8 error is generated
could someone help me? 
maybe replacing some extensions but I have no idea which ones and the substitute blocks
Hi, when adding the Onesignal Push extension and trying to generate the apk I get error: d8 failed

Post the logs so I can help
Before the update, the APK was generated normally. However, after the Kodular update, I started getting the “Run D8” error when trying to generate the APK. It seems to happen when I use the paid OneSignal extension in the project.
Kodular is unable to compile this project.
The compiler error output was

That’s a general Kodular issue and not a specific extension issue… see also the orher posts in this thread
Taifun
I’ve researched some topics, but I haven’t found anything that clarifies whether there’s a solution for this issue caused by the new Kodular update. Do you know if they’re already working on a fix?
another Kodular sore point.
the platform is collapsing right before our eyes. sometimes their build server doesn’t work for several days, or there are problems with the build itself. No one seems to be doing this. There is a strong impression that no one is dealing with the platform’s problems at all. 
similar error messages began to appear regularly. from my experience, I will say that I restart the build and after several unsuccessful attempts, the build completes successfully.
After the new update of kodular, many extensions from the utility providers will have Run D8 error, the only way is to create an aia file and clone the project, then delete each extension one by one to determine if there is 1 or more components causing the error. From there, ask the provider to update the library again. Kodular has so many errors :((
Saw few other posts on the community also but not found any valid solution yet. I’ve few pending projects.
Even old projects also not exporting. @KodularCreator kindly fix this issue, we are tied and tired with these errors and bugs.

Everything was working and I was issuing the apk file without any problems and I did not change or add anything new in the project. Why is it not working now?

I experienced the same thing
I experienced the same thing too
Make sure all your extensions are up to date.
@Taifun mentioned that the issue is with Kodular itself, while you indicated that it may be due to an outdated extension. Before the Kodular update, the APK was generated normally, but now I receive the ERROR: d8 when attempting to compile. However, when I remove the OneSignal extension from @iamwsumit , I can generate the APK without this error.
If this is related to the Kodular update, I would greatly appreciate it if the @Kodular could investigate and provide a solution. If it is an extension issue, I would be very grateful if @iamwsumit could update it, allowing the project to continue smoothly.
Thank you so much for your attention!
