Jekyll serve now fails but the trace message does not seem helpful to me. These are the steps I have taken so far and the error messages as well as the crucial environment versions. Mac OS X was recently updated so it must have something to do with that, but I see that I am still running Ruby 2.6.1. I did some searching here and on SO without much related to my actual trace error.
MacOSX Big Sur 11.4
Updated XTools had missing extensions, so I updated it.
$ which ruby
/Users/jhogue/.rvm/rubies/ruby-2.6.1/bin/ruby
$ ruby -v
ruby 2.6.1p33 (2019-01-30 revision 66950) [x86_64-darwin19]
RVM does not have 3.0 installed as an option — is it required for Jekyll 4.2 (which I am running as well)? Bundle has been updated twice. Gemfile.lock has been deleted and recreated.
$ jekyll serve --trace produces:

I added execjs to my Gemfile (which was not formerly present) and ran bundle update. Output confirms I am Using execjs 2.8.1. Still fails quietly when running jekyll serve without a trace command:
$ jekyll serve

------------------------------------------------
Jekyll 4.2.0 Please append `--trace` to the `serve` command
for any additional information or backtrace.

Now I’m stuck and do not know what to try next.
