Error opening MIDI file - Dorico 4

Hello, I’ve been trying to import this simple MIDI melody exported from Ableton but Dorico won’t open it and displays a “Error opening file”. The “Show Details…” only shows the file’s location.
I have tried to copy the MIDI track and re-export it from Ableton but it doesn’t help. Cropping the clip and deleting muted notes didn’t help either.
Cubase and Sibelius are able to open the file. Re-exporting the MIDI file from Cubase and Sibelius still result in a file that Dorico won’t open.
Anyone could help me figure out what is going on with this file? I just exported about a hundred MIDI files from Ableton to Dorico and they all work fine, except this one.
thanks!
Florent
