Sorry for the late response, I was making the most of the long weekend. My computer just updated Windows to build 26300.8497 and the right click menu is working again. Thank you for working with me on this.
Setup Windows Sandbox and installed Start11v2 v2.72 on the VM. With the vanilla installation, the right click menu shows correctly. I backed up and transferred my settings file to the VM and imported it. I had the same outcome. The menu still shows up correctly. The Windows version in the sandbox is: Windows 11 Enterprise Insider Preview Build 26100.8493.ge_prerelease_im.260513-1839 Please let me know if there's anything else I can do. Thank You.
When Start11 is active and the Show Win+X menu when right clicking on the start button rather than the Start11 one is toggled to the On position, right clicking on the Start button does nothing. If I toggle the option Off, the Start11 right click menu appears. Taskbar is set to bottom, left aligned. This worked correctly until updating to v2.7. Currently on Start11 v2.71. Windows version is Windows 11 Pro Insider Preview - 25H2, build 26300.8493.
