Add an effect (like a fade) in premiere and the clip turns invisible.

Tl.dr
I can't add a simple effect, if I add a simple fade to a clip the clip won't show in the preview. 

I have had huge problems editing my latest project with countless hours of finding solutions. I have tried on two diffrent computers (both very competent, a PC and a MacBook Pro i9 2020) and it seems to be a software issue. My latest problem is that any effect, if even slightly animated, will turn the subjected clip invisible.

Example clip:

If anyone knows how to resolve it, it will leave less scars on my career. Thank you.

*It won't even show when you export it.

Sublime,

Sorry. Could you be more precise? Like, how are you fading the clip? To black? With which, a dissolve or by fading opacity? Any blending modes applied? Let us know more, please.

Thanks,
Kevin

I just animated the opacity 100 - 0 and the whole clip dissapears. But even if I animate 100% - 99% the clip stops showing altogheter. Doesn't seem to matter which effect I add, I wanted to add a gradient wipe from the beggining but the same problem occurs. Normal blending mode, the most simple thing you can do. 

If you want to see it in action I attatched a link with a recording I did on my iphone.
