Could not load library "libmpfr"

I’m confused by this issue: Windows: packages that `ccall` `:libmpfr` by bare name fail since #63686 · Issue #63849 · JuliaLang/julia which is declared closed.

CI on XLSX.jl now fails on both Julia nightly and Julia pre, and the message is:

ERROR: LoadError: could not load library "libmpfr"
  The specified module could not be found. 
  in expression starting at C:\Users\runneradmin\.julia\packages\IrrationalConstants\RokwY\src\stats.jl:26

My declared compats are:

[compat]
Colors = "0.12, 0.13"
Dates = "1.10"
FileIO = "1"
OrderedCollections = "1, 2.0"
Parsers = "2.8, 3"
PrecompileTools = "1"
Printf = "1.10"
Random = "1.10"
StyledStrings = "1.0.3"
Tables = "1"
UUIDs = "1.8"
Unicode = "1.10"
XML = "0.4.6"
ZipArchives = "2.5"
julia = "1.10"

and in tests:

[compat]
Aqua = "0.8"
Colors = "0.12, 0.13"
CSV = "0.10.15, 1"
Distributions = "0.25.0"
FileIO = "1"
OrderedCollections = "1, 2"
Pkg = "1"
StyledStrings = "1.0.3"
Tables = "1"
XML = "0.4.6"
ZipArchives = "2.5"
julia = "1.10"

Is this a temporary issue that will fix itself or is there something I must do myself to fix this? Do my compats need updating (Dependabot is silent so far)?
