This just started happening today. Been a couple of weeks since I last used Vegas Pro 23/365. Tried my previous versions 21 and 22 and they also crash on startup. Tried the vcomp140.dll fix but no go there. Claude had me jumping through a few hoops but no luck there also.

All software up to date.

Processor    12th Gen Intel(R) Core(TM) i7-12700H (2.30 GHz)
Installed RAM    32.0 GB (31.6 GB usable)
Intel Iris Xe and Arc 16GB

Any help most appreciated.
