I believe a work-around is:

Download the following two files and place them in a folder without a space in the path, (like C:\temp) :

https://repo.msys2.org/msys/x86_64/msys2-keyring-r21.b39fb11-1-any.pkg.tar.xz
https://repo.msys2.org/msys/x86_64/msys2-keyring-r21.b39fb11-1-any.pkg.tar.xz.sig

then run:

ridk exec pacman -Udd <full path to the xz file>

If using c:\temp:

ridk exec pacman -Udd C:/temp/msys2-keyring-r21.b39fb11-1-any.pkg.tar.xz

EDIT: 32 bit Ruby or 32 bit system? The above files may be wrong for a 32 bit system. I don't know if the 32 bit systems are supported?

32 bit system is:

https://repo.msys2.org/msys/i686/msys2-keyring-r21.b39fb11-1-any.pkg.tar.xz
https://repo.msys2.org/msys/i686/msys2-keyring-r21.b39fb11-1-any.pkg.tar.xz.sig

Yes its for 32 bit Windows operating system (Window 7 sp1),,

I tried above steps but I am still getting below errors;

You might have run into the problem which occured after a change of the guard of the msys2 maintainers. It's explained here:
https://www.msys2.org/news/#2020-06-29-new-packagers

I include the text from the webpage in case the URL will go out of service at some point:

We have prepared the following steps to verify and install the new keyring manually after which you should be able to use pacman -Syu again:

$ curl -O http://repo.msys2.org/msys/x86_64/msys2-keyring-r21.b39fb11-1-any.pkg.tar.xz
$ curl -O http://repo.msys2.org/msys/x86_64/msys2-keyring-r21.b39fb11-1-any.pkg.tar.xz.sig

$ pacman-key --verify msys2-keyring-r21.b39fb11-1-any.pkg.tar.xz.sig
==> Checking msys2-keyring-r21.b39fb11-1-any.pkg.tar.xz.sig... (detached)
gpg: Signature made Mon Jun 29 07:36:14 2020 CEST

gpg: Good signature from "Alexey Pavlov (Alexpux) alexpux@gmail.com" [full]

# pacman -U msys2-keyring-r21.b39fb11-1-any.pkg.tar.xz
If you can't even import the key and the above command fails like this:

error: msys: key "4A6129F4E4B84AE46ED7F635628F528CF3053E04" is unknown
:: Import PGP key 4A6129F4E4B84AE46ED7F635628F528CF3053E04? [Y/n]
[...]
error: database 'msys' is not valid (invalid or corrupted database (PGP signature))
loading packages...
error: failed to prepare transaction (invalid or corrupted database)
... you have to convince pacman to not care about those databases for a while, for example like this:

# pacman -U --config <(echo) msys2-keyring-r21.b39fb11-1-any.pkg.tar.xz
If you still see signature errors, resetting your pacman key store might help:

# rm -r /etc/pacman.d/gnupg/
# pacman-key --init
# pacman-key --populate msys2
