I m seeing in logs almost on every file i play this error: ERROR : 4kfiles/Dunkirk.2017.2160.mkv: vfs cache: failed to _ensure cache EOF. No issues in playing tho.

I confirm that error is harmless, but annoying!

I've made a fix for that here which I'll stick in 1.53.1 at some point.

v1.54.0-beta.4745.27b9ae4fc on branch master (uploaded in 15-30 mins)
