1. For a period of 3-5 year, I'll proceed with the jail. I think you can have limited Internet access in jail, but this might not be the case in your country. Check with the authorities. Otherwise, proceed by selling your business quickly and put the money is a safe index fund. With a 5% return, over 5 year, this means 27% return.
2. If the period is hilariously long, like 20 years, I'll advise you to escape. There are many ways from seeking Asylum to illegally crossing the borders. Some people will discourage you to illegally cross the border, but I guess it's better than spending 20 years in some prison with no real-life contact.
3. I remember there was a discussion about changing one identity. It might sound like movies, but you may want to look into that. You can also just hide in your country, and keep looking for possible escape solutions/countries.
