Steps to reproduce this issue

When dubbo.provider.export=false is set, the project will report an error when starting up, but it does not affect the project running.

What you expected to happen

If "dubbo.provider.export=false", then this "ExporterDeployListener.onModuleStarted" should not be called, right?

Anything else

the project params:

dubbo.protocol.name=dubbo
dubbo.protocol.serialization=hessian2
dubbo.protocol.port=27001
dubbo.protocol.threads=220

dubbo.application.name=xxxx-dubbo-server-${spring.application.name}
dubbo.application.register-mode=instance
dubbo.application.metadata-service-protocol=dubbo
dubbo.application.protocol=dubbo

dubbo.provider.export=false
dubbo.provider.token=true

dubbo.registry.protocol=zookeeper
dubbo.registry.address=${zookeeper.address}
dubbo.registry.file=/root/.dubbo/${spring.application.name}
dubbo.registry.use-as-config-center=true
dubbo.registry.use-as-metadata-center=true

You can use Dubbo 3.3, which already solves this problem
