Hello there @2350lev!
Investigating around the community, I can confirm this is a known issue between the AutomatedPerfTesting plugin and UE 5.5.4.
Checking with my peers, the first step would be to ask if the plugin is needed 100% for your build, as disabling it during packaging would resolve the error. In case it is required, a possible workaround would be to backup its content, restore the version from 5.5.0, disabling file replace during buid, and try to pack the project again.
