Yeah VASAviation posted a video with ATC audio and the runway/taxiway layout [0], which definitely suggests that they were just taxiing and turned wide. Seems most likely to be pilot error, maybe with poor visibility or braking performance or something contributing (weather seems to have been fine but I don't want to pass judgement without all the details).
