Diesel fuel system on other 3500 years
No other 3500 model year has enough reports of diesel fuel system for a sheet of its own. See every 3500 year.
What this problem usually is
Diesel fuel system complaints have a pattern of their own. Many are waiting on a recall part that isn't available yet. Others describe the truck stalling or losing power, a fuel smell in the cab, trouble right after refueling, or a diesel particulate filter that keeps clogging. Injector replacement comes up often.
What got replaced
Owners who name the part that was replaced mention the fuel filter (4 reports).

Is this a known problem?
The manufacturer has sent NHTSA 1 service bulletin or notice for the 2019 Ram 3500 that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.
Diesel Fuel Pump Failure and System Contamination This bulletin involves inspecting for fuel pump failure and fuel system contamination. Also fuel system cleaning and fuel system kit replacement.

Should you keep driving it?
This page can't tell you that. 1 of 27 reports involved a crash and 3 people were hurt. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
