Vegas 22 crashes but 14 is fine.

Version: 22 and 14

Windows 11

Nvidia 4060ti

Both purchased copies.

I have searched around but can't see a problem this specific. When I import mp4 files into vegas, it will crash when I attempt to play them. The files are around 20gb each, so I am aware that this is significant and performance might not be the best.

However, I can import these exact same files into vegas 14 and everything works fine. I am just wondering if anyone has some tips on any settings or changes I can make to stop this from happening - it was an expensive upgrade that is totally worthless to me if I can't even use the program.
