I don’t particularly think that without Mbappe, PSG will face hardships. At least not in Ligue 1. Football is not played by 1vs11, rather it's a team game. Yes, it can be argued that Barca became arguably worse after Messi's departure but they weren't really that good when he left.
If you talk about PSG, they have good finances, a solid coach, and a decent amount of players in the club still. If they play their cards right, they can still dominate the Ligue 1.
About the UCL, Luis Enrique would need good reinforcements, as they couldn’t win it even with Mbappe. He needs to sign a proper striker and then need to balance out the whole squad, and if they do that, they might do well in the knockouts.
You speak on PSG's "resilience" in Ligue 1 without Mbappé. In a league they already own, PSG become a predictable team without Mbappé's electrifying pace and finishing. It like viewing a highlight reel without of the highlights. PSG's Champions League failures aren't about missing a single player, it's about lacking a cohesive game plan. It like having a squad of all-stars unable of playing together. There's more to Luis Enrique's problem than buying a star striker. Will PSG so at last get their act together or collapse under pressure? Honestly, who knows? One thing is certain, though: throwing money at the issue won't help. It's about strategy, teamwork, and a lot of guts generally
