Hi Trevor,
Thanks for providing these details. It seems the Windows build listed, 25H2 OS Build 26200.8524, could be a Windows Insider / preview build. Can you confirm whether the HP tablet is enrolled in the Windows Insider program? (Should say in Settings -> Windows Update -> Windows Insider Program).
Please know that we do not provide official support for beta, preview, developer, or Insider builds of Windows. That would be the first thing I would want to rule out. For reference: https://support.stardock.com/space/SHC/1261010948
For further insight, I can tell you the Microsoft Debug Manager prompt usually means something in the installer process crashed and Windows is offering to debug it. It is not normally the cause by itself.
You can:
1. Check the exact Start11 installer file version you are running (right click Start11v2_Setup.exe -> Properties -> Details tab). I would expect it's the same file version that worked on your Desktop.
2. On your tablet, you can also check Event Viewer under Windows Logs -> Application for any error at the same time the install fails. The faulting application details from that event could help to narrow down the cause.
