We had a crash in the Conductor library 3.0.0-rc2

It happened on a Sony Xperia XZ2 with Android 10

Here is the complete stacktrace:

Fatal Exception: java.lang.NullPointerException

Do you have any recommendations? Is it maybe fixed in some recent 3.0.0-rcX versions?

Thanks in advance, Christian

It's hard to tell with the obfuscated stacktrace, but I think this is a duplicate of #567, which was fixed with #629
