I am not a master in pacman but that the command sequence which helped me

pacman-db-upgrade
pacman-key --init
pacman-key --populate msys2

Then I ve got this problem
warning: mingw-w64-x86_64-gdb: local (7.8-1) is newer than mingw64 (7.6.2-1)

Which was solved by
pacman -Syuu
pacman -Syu

If nobody has any problems of the same kind, the issue can be closed.

Thank you for keeping updating the repositories.
