I just downloaded a Win10 ISO (x64 UK) using official MS Download Tool. Tested using Ventoy 1.0.35. Legacy and UEFI64. No issues.
I would suspect your ISO (check the checksum of the file ON THE VENTOY USB DRIVE and compare with expected checksum), the PC you are booting it from (is it a fake?), or your USB drive and the way you prepared it.
Many others would be reporting a problem and they are apparently not...
Can you give more details?
Legacy or UEFI?
Type of ISO (dual, country/language, etc.) how made.
