What do you mean it works correctly in development mode? the log looks like a runtime error rather than a compiling error.

In debug mode it works correctly, the errors occur when I run the exe, did I perhaps compile the package incorrectly?

In the same project I also use ucanaccess to access a database, is it possible that this conflicts?

To build standalone package, try adding this property
B4X: 
#PackagerProperty: VMArgs = --add-opens b4j/org.bouncycastle.jcajce.provider.asymmetric.ec=java.base
