I’m not telling you it’s okay, I’m making suggestions as to what you could do about it.
There is a tension between what makes a good digital map and what make a good tabletop map. Digital maps want eye candy, and it’s easy to make the grid as clear or hidden as you like to suit your play style. A good tabletop map is bi-coloured and as simple as possible so it can be easily reproduced with pencil and paper.
This map is clearly intended to be a VTT map, not a tabletop map.
I found Vecna: Eve of Ruin particularly frustrating as it switches between VTT and tabletop style maps at random, so however you are playing the next map is going to be in the wrong style.
As for this particular map, the area is only about 50 miles across, with lots of habitation. It’s more a ramble in the South Downs than the Oregon Trail. It’s not like anyone is going to run out of food and starve. You can give the players a copy and say “where do you want to go” then tell them how long it takes.
