Importing Canon C70 10bit 4:2:2 crashes the whole computer.

[#1]

Hi everyone, I'm a professional video editor, and we've recently started shooting with the new Canon C70. The big problem that appeared immediately after we imported the 10bit 4:2:2 is a Premiere freeze and subsequent computer crash (not necessarily in that order). And it only happens when importing the 10bit 422 footage. Other formats on C70 import just fine. 
So far I've tried:
Updated Premiere to the latest version

Cleared cache and plugins

Reset the preferences. 

- I work on iMac, Catalina OS. And have never experienced any issues when working with other cameras and formats. Even something like CRAW and other raw formats work fine. 
Thank you for your help!

I see from other posts on this forum that this has been an issue since 2017 Panasonic GH5 release. Why is free DaVinci working perfectly fine while the program I pay for underperforms on such basic issues as 10bit video. Smh.

I'm having the same issue. Have you solved this yet?

The only solution I have is to reencode all of the files to ProRes using media encoder. I found it to not be worth the time and just shoot 8 bit now. Premiere sucks. And Adobe's support sucks.
