Try this, it worked for me and some other people:
Uninstall ghc and tidal, completely delete the c:\tools and c:\Users\<user>\AppData\Roaming\cabal folders and reinstall by hand:
choco install ghc --version 8.10.7
choco install mingw
choco install msys2
Add c:\tools\msys64\usr\bin to the system path and reboot.
Finally:
cabal install tidal-1.8.1 --lib
