Hello
I could reproduce this error with different Win10 ISOs (from v. 2016 to 20H2 in english / german language).
Just take any original install ISO file from the Microsoft download.
Copy the content to disk. (e.g. use copyPE command)
Add any file to the boot.wim to increase its size to ~1100MiB.
The install.wim can be deleted.
After recompiling the ISO file is no longer bootable from Ventoy (in UEFI mode), although it can boot from other media.
As said before, it is not the size of the ISO file but the size of the boot.wim file that is important.
This way everyone here on the forum can understand / repeat the process and draw their own conclusions.
Best Regards T.
