error when opening texture packs form pc

[cubie cube cube 3]

I was making an animation and I wanted to open a schematic from Minecraft using a texture pack the was installed on my pc and this error message popped up

 

win32 function failed: hresult: 0x80070057

I tried searching it up on the internet but found nothing relevant to the situation

Is that a Mine-Imator or a Minecraft or something else issue ?

If it's MI : What do you mean by "open a schematic from Minecraft using a texture pack" ? That doesn't make really much sens for me. Plz be clearer so we can help, thank you.
