Using Wayback Machine on the NRE disruption pages gives this for 19th May 2023 (13:00):
Severe disruption b/t Lancaster and Preston
Route(s) affected
Avanti West Coast between London Euston and Glasgow Central / Edinburgh
Northern between Manchetser Airport and Barrow-in-Furness / Winderemere, and also between Lancaster and Carlisle
TransPennine Express between Manchetser Airport and Glasgow Central / Edinburgh, and also between Liverpool Lime Street and Oxenholme Lake District
Description
A fault on a train between Preston and Lancaster means all lines are blocked. As a result, trains may be cancelled or delayed by up to 60 minutes. This is expected until 16:00.
OP, where were you going to and from? Do you remember at what time?
EDIT: Forum thread from the day
Does anyone know what’s up with the large number of train cancellations (>50% of those scheduled, seemingly) from Manchester Piccadilly to the airport? Have a flight tomorrow morning and am wondering if I should give myself extra time to get over there.

EDIT 2 - Reread OP’s first post, sorry. So yes, I assume it’s one of the cancelled Man Picc to Airport services.
