Unable to stream B6 gameplay

Hi

when attempting to capture the game in TikTok Studio, meld or whatever it is the bf.exe  becomes unrecognisable.
Sometimes it captures for about 20mins then the game looks like it’s frozen to my audience and I’m unable to try and recapture the game even when deleting the source and trying again.. 

it also happened with others who were sharing in discord too as a test. 

Tried verifying the files in steam. Computers more than capable as it 9800x3d, 64GB DDR5 and RTX4090.

Don’t have the issue with any other game I stream. 

The streaming app works still, it’s just the game source that is the issue

Any help would be great.

Thanks
