[Q] Link2sd not working crashing app's on cm12 (5.0.2) topic

Hi I have a big problem with link2sd on my galaxy s5 g900f with a 128gb sd card and cm12 for klte (android 5.0.2) build 12-20150223-klte. First at all when I link a app (apk, dex, lib, data or obb) to my ext4 partition the app stops working and craches everytime at start of the app (it worked before linking to seconde partition) I also rebooted my phone after linking and it stil doesnt work. So then I tried unlinking the app and it stil doesnt work even after a reboot. Than a deleted the app and I [tried] to reinstal the app (also after a reboot) and than I get a unknow error of google play store and it doesnt want to instal the app again. So a deleted the play store data and cache and searched my internal memory of rests of the app in android/data and android/obb folder and there was nothing so than I reboted my phone and tryed again to instal the app and I can't stil not instal the app.

I make a screen recording of my problem you kan see it on this link:

Also my sd card's first partition is a exfat of +-64gb for my documents, and the second partition is the ext4 of also +-64 gb fore my games and apps for link2sd

Thanks!
