Go to this page: https://www.audacityteam.org/download/windows/
Wait a few moments and it should automatically offer to start a download - cancel / dismiss that download (that’s the 64-bit version).
Scroll down the page a bit to find the Audacity 3.0.4 32 bit installer and download that.
Uninstall your current version of Audacity,
then install the 32-bit version.
