VRChat crashing on startup?

Hey so, this is on behalf of my friend.
Her VRChat used to work fine, about a year ago, but now whenever she opens it she gets the above error message.

I’ve taken her through this article: https://help.vrchat.com/hc/en-us/articles/1500002247921-VRChat-keeps-crashing-or-has-issues-launching-properly
And nothing’s worked.

If anyone has a fix that’d be great.

Also her PC is old
She’s running a AMD Athlon™ II X2 245 Processor with an NVIDIA GeForce GT 630
Which very well may be the reason it’s crashing, just want to make sure.

Thanks in advance!!!
