LoKi functors, as well as some other tools, assume they are owned by a DVAlgorithm and use the tools configured within. Typically, BPVIPCHI2() assumes the existence of the geometry tool. This was reported bu @amathad in https://gitlab.cern.ch/lhcb-dpa/project/-/issues/173 following https://mattermost.web.cern.ch/lhcb/pl/tddzihtuitbdtq1ifajt4pj6zh.
There's no point fixing LoKi as eventually its functors will be replaced by ThOr. BPVIPCHI2 is already. In the meantime make sure there is no crash but exit gracefully instead. With this MR the message is
FunctionalParticleMaker.LoKi::Hy... FATAL Exception with tag=Gaudi::Utils::getIDVAlgorithm is caught

I suggest to backport to run 2.
