i know can delete avd , create new one. there way fix problem existing avd without recreating it?

i managed fix problem removing lock file.

the lock file located in avd directory ( in case /home/developer/.android/avd/nexus_5_api_25.avd visible in verbose output posted in qustion) , named hardware-qemu.ini.lock.

emulator have been running without problems once removed file.
