This is most likely what’s causing it. Respawning players with verse has long been inconsistent and a scary thing to do.
A bug I had reported last year was marked as fixed for the upcoming new season update while the report was about some UI inconsistencies with respawned agents maybe the fix also addresses your DBNO case.
A known workaround is to Eliminate them after they are respawned by changing them to a team or class with infinite respawns and have them go through the normal respawn sequence which should solve these kind of bugs
