I kinda wonder if that is the case given that it is Nuendo 4 on a modern PC.
That aside, cracked or not: OP Nuendo 4 is seriously old. It was released in 2007 so we are talking XP days (Vista had just come out). While XP era software CAN work in Windows 10 (by the way if you have a 12th gen CPU you want to move to Windows 11, it supports them better) it isn’t always going to. A lot has changed in the intervening 15 years.
If you have a legit copy, I’d suggest seriously considering an upgrade. It is expensive, $400 right now, though upgrades go on sale a few times a year and you can probably get it for $200. It is well worth it as not only will it work better on newer computers, but it has a ton more and better FX, as well as being 64-bit which means support for new plugins as most aren’t 32-bit anymore.
If you are using a pirated/cracked copy, then this forum is not the place to ask about it.
