Try removing your after startup microflow from the project and run that manually after the runtime has started, as the error states something throws an error during after startup, which is pretty difficult to debug.
It seems the problem is in the AppCloudServices:
Caused by: java.lang.NullPointerException: null at appcloudservices.OpenIDUtils.<clinit>(OpenIDUtils.java:15) at
which times out
com.mendix.systemwideinterfaces.MendixRuntimeException: akka.pattern.AskTimeoutException: Ask timed out on
[Actor[akka://MxRuntimeSystem/user/dispatchSupervisor#-74790800]] after [604800000 ms] at
If you are running locally or on premise, you can remove this from the after start up flow. Alternatively, you might be blocking outgoing calls to the Mendix service, so you can try to allow such calls.
Thx guys. It's running now
