failure at the end

I would like to give some current error feedback in order to actively contribute to the improvement.
I wanted to reinstall Win11-Pro on a Lenovo Thinkpad E531 (Intel Core i5) with SSE4.2 but without TPM module using the latest Flyoobe.exe.
I had downloaded a Win11-Pro 64bit iso via this tool and (as stated in the help) initially clicked on "advanced ..." to install Win11 complete new and checked the advanced mods box. Entered the correct image and navigated through the app without errors so far. I uninstalled most of the included apps and also Onedrive, which caused the first error.
But, with or without uninstalling Onedrive: the arrow to the right on the right side of the program window no longer works (it simply doesn't react, even after waiting a while).
This seems unusual. I close the program and boot with the USB stick I have just patched (hopefully correctly). Almost before the actual Win11 installation starts (after corrct booting), the message appears that the PC is incompatible with Win11 and I can't continue, only close or go back. And this after about 20' of work.
It worked perfectly with Rufus immediately afterwards (using the same iso image and the same USB stick!).
What is wrong?

Start at the FlyOOBE.exe workflow using the reported Windows 11 Pro ISO, advanced mods, and USB stick on the Lenovo ThinkPad E531, reproducing both the unresponsive right-arrow step and the installation incompatibility message. Compare the same ISO and USB behavior with Rufus; done means FlyOOBE completes the workflow and its patched media proceeds past the reported Windows 11 compatibility block.
