blavaan upgrade fails on Windows 12 native R

update.packages('blavaan') fails on my windows 12 home system running native R 4.3.2 Oddly, the update went fine on my University research desktop, also running windows 12 and R 4.3.2. This appears to be a configuration file problem, but the error message is not very helpful.
Thanks to anyone with a suggestion on how to fix this problem. Larry Hunsicker

Reinstalling the V8 package didn't help.

First check if you really need to compile the package from source, and install the binary package if you can.

Otherwise this seems to be a problem with the blavaan or the rstan package, so I suggest that you open an issue in their issue tracker. They can probably give you the best advice.
