1) Where did you get the install media from?
2) Are you following the instructions in both the preview guide and the unofficial guide?
Looks to me that you don't have the latest Tech Preview version installed. Versions older than Professional Version e.x.p (20191287) )do not have Windows as an operating system that you can select for a virtual machine. Those older versions also do not contain VMware Tools that support Windows 11.
Check the version of the Tech Preview by clicking from the menu bar VMware Fusion > About VMware Fusion. It should should show Professional Version e.x.p (20486664)
If that's not the case, please download and install the latest Tech Preview version from here https://communities.vmware.com/t5/Fusion-Tech-Preview-22H2/ct-p/3022 and download and read both the Tech Preview Testing Guide and unofficial Tips and Techniques guides found here: https://communities.vmware.com/t5/Fusion-22H2-Tech-Preview/tkb-p/160003
