I have upgraded the provided defect file (v8.7) to energyplus v9.4.0 and got an actual hard crash. So I went ahead and created an issue at NREL/EnergyPlus#8412. I will report back if a resolution is found.

Workaround: The problem is explained in more details on https://github.com/NREL/EnergyPlus/issues/8412#issuecomment-740642837, but basically you want to NOT autosize the tank (volume and height at least) for now.

For eg, given that your WaterHeater:Sizing objects indicate "Nominal Tank Volume for Autosizing Plant Connections" of 30 m3 for HW ST and 0.1 m3 for HW Aux, do something like this in the WaterHeater:Stratified:
WaterHeater:Stratified,
HW ST, !- Name
General, !- End-Use Subcategory
30.0 , !- Tank Volume {m3} <= Enter hard value
2.0, !- Tank Height {m} <= Enter hard value
[...]
WaterHeater:Stratified,
HW Aux, !- Name
General, !- End-Use Subcategory
0.1, !- Tank Volume {m3} <= Enter hard value
1, !- Tank Height {m} <= Enter hard value
[...]
With that change, the file wile run to completion.
