UHD Files stop working after a few seconds of playback

My vero 4K+ (osmc 19-4 update) is playing my 4K movies only for a few seconds. After that it is stuttering and finally playback is freezing. I uploaded a log file… https//paste.osmc.tv/ upepezurir

Suggest to try to play the movie from a USB disk to identify if the problem is related to the NFS client
