Vine weevil grubs, Clarington. They are definitely the reason your strawberry plants died.
The best thing to do is wash all soil from the roots of any remaining plants and plant them into fresh compost.
Put a sheet of weed fabric or something similar down in your garden and tip the compost with the grubs in on to it then spread it thinly. The birds will then have a feast and eat those grubs. Don't re-use that compost for potting even after the birds have done their job but it will be fine spread on your borders as vine weevil have many enemies in garden soil.
