took a quick look and noticed something: the moist air flow rate is 50kg/s (that's a LOT for air flow), while the port area is ~2500 mm^2. This would amount to about 20000m/s air speed (!!!!), which doesn't make sense to me. The local speed of moist air is part of the enthalpy flow calculation, so maybe this is why? Could you please check the parameters and inputs, make them reasonable and see if the problem persists?
issues on Heat exchanger in simscape TL-MA

the model created seems not to behave phisically correct: heat exchanger reduces both temperature of TL and moisture air.
it should heat up air, cooling down fluid instead.

Setting reasonable parameters to discribe the nominal conditions for the heat exchanger seem to resolve the issue. Pay particular attention to units and type of information needed (mass flow vs. volumetric flow). The port size matters as well because the local velocity calculated based on port size and mass flow is also part of the energy flow calculation.
