No, i donīt think so.
If you have a faulty PRV (Pressure Regulating Valve) or 10HA (PRV Control-Solenoid) the pressure "usually" decrease. But this is only one sorce of bleed. The other engine would maintain the neccessary pressure to hold the cabine.
But your v/s "increase"!
I would blame the CPC (Cabine Pressure Controler) or the OFV (Out Flow Valve).
What did the PFR say?
Any ECAM warnings or fault messages related to ATA 21?

P.s.: You ask for PRV or 10HA
2 so i think you have a fault message like "PRESS REG-V 4001HA2 OR SOL 10HA2 OR SENSE LINE"
But if you habe no ECAM warnings related to Bleed pressure like "AIR ENG 2 BLEED ABNORM
PR" or the crew observed unusual pressure of this engine, you can (my experience) disregard this fault message. You can see this fault message very often in the PFR or PLR (Previous Leg Report) of the BMC (Bleed Management Computer) on normal working airplanes.
