It is also Windows Server 2022 with GUI, a quite fresh installation. The 
checks run in a docker container (also WS2022, 
mcr.microsoft.com/windows/server:ltsc2022, without any manually 
installed fonts).

Actually there is no manually installed software there, all that is 
installed is (in this order):

https://svn.r-project.org/R-dev-web/trunk/WindowsBuilds/winutf8/ucrt/r/setup_miktex_standalone.ps1
https://svn.r-project.org/R-dev-web/trunk/WindowsBuilds/winutf8/ucrt3/r/setup.ps1
https://svn.r-project.org/R-dev-web/trunk/WindowsBuilds/winutf8/ucrt3/r_packages/setup_checks.ps1

plus R and R packages.

I assume you can reproduce on Winbuilder, and so perhaps you could 
create a version of your package with a lot of instrumentation/print 
messages and submit there to find the cause? Possibly also an 
instrumented variant of systemfonts.
