I am having the same problem. Since the base::system call works, I tried to rewrite my own small orca function with base::system instead of processx::run and it works fine.

p <- plot_ly(mtcars, x = ~mpg, y = ~wt)
file = "plot.png"
format = tools::file_ext(file)
debug=verbose=safe=F
b <- plotly_build(p)
plotlyjs <- plotly:::plotlyjsBundle(b)
plotlyjs_path <- file.path(plotlyjs$src$file, plotlyjs$script)
if (!is.null(plotlyjs$package)) {
  plotlyjs_path <- system.file(plotlyjs_path, package = plotlyjs$package)
}
tmp <- tempfile(fileext = ".json")
cat(plotly:::to_JSON(b$x[c("data", "layout")]), file = tmp)
args <- c("graph", tmp, "-o", file, "--format", 
          format, "--plotlyjs", plotlyjs_path, if (debug) "--debug", 
          if (verbose) "--verbose", if (safe) "--safe-mode")
base::system(paste("orca", paste(args, collapse = " ")))

Thank you so much @trafficonese for troubleshooting this! It seems like Orca itself is fine but the wrapping in https://github.com/ropensci/plotly/ is not. Could you open an issue over there?

This finding may be the reason behind issues #302 #306
