I've just installed my new pc but when I tried to launch vegas I had exactly the same problem as this person:
I launch vegas, the preview file opens and the software crashes exactly like the video.
(it turns out that this person never managed to solve this problem)
I have more or less the same configuration as him (exactly the same ssd, 64go ddr5 ram and a 3080TI). I've tried the answers on this site and, like him, nothing works...
I can provide you with what you need but no log file is created it seems to me.
Thanks in advance!
