Engine Prime 1.5 invisible tracks

Hello guys,

I downloaded the 1.5 version of engine prime. Is it only me or this update is a real untested ■■■■ ?

All my tracks are invisible in the software :

If i click on sync manager on the bottom left, software crash.

I can’t analyse or load any invisible tracks. I’m on windows 10 but happens aswell on mac.

everything works well on older version.

Any idea or should i reinstall the old version waiting Engine team test the software ?
