Windows Setup only needs ~10gb of free space to start an upgrade from Windows 10 to Windows 11, and the installer checks (and fails) if you have less than 10gb available. No BSOD during the process. You probably have a faulty SSD.
Second, inside the %systemroot%\Installer folder there are cached msi installers from all msi programs that you have installed on your computer.
Try entering inside this folder and hover your mouse over the msi file to see the description of the installer. This way you will see what programs are occupying all the space. If you delete the files inside the %systemroot%\Installer, you won't be able to uninstall/repair them.

Unfortunately the Installer folder contains both buffer, temp and used data, for which is not recommended to delete. Normally, being able to complete the upgrade will successfully remove all unnecessary post-upgrade file, so I would suggest to focus in troubleshooting the upgrade issue.
On the other hand, there are certain 3rd Party tools, such as PatchCleaner, that many users of the community has flagged as useful, but is not provided or supported by Microsoft.
