Haha hoho and heehee. I DOOD IT! Ventoy (and Bookwormpup64) is working again even though I have the
Window update that broke Ventoy. You are going to spaz when you see how easy it is to fix. No need to disable Secure Boot.
1) Get an ISO of the newest Ubuntu. Linux Mint doesn't have the mmx64.efi file.
2) Copy BOOTX64.efi and mmx64.efi from EFI/BOOT folder to the VTOYEFI partition EFI/BOOT folder. The partition can be made visible in Windows by using Storage Settings or I suppose This PC/Manage to give it a drive letter. You can extract the files from the ISO with Winrar. Watch the filenames. BOOTX64.efi needs to be just that.
3) Rename grub.efi in /EFI/BOOT as grubx64.efi.
You may kiss my big toe now. lol
