Help! A fatal error occurred when running Fusee. Package3 seems corrupted.

"A fatal error occurred when running Fusee. Package3 seems corrupted."

This is the message I get when launching Atmosphere for the first time after migrating from SXOS using the rentry guide. How do I fix this?
Firmware 11.0, Launch Edition Switch

Please help, and thank you!

Someone suggested I use Hekate instead of Fusee. How do I do this? Is this what I should do?

Edit: This worked. Thank you.

Did you download the latest Atmosphere?

Hi, i started from the beginning. Formatted SD card and installed Atmosphere. Works fine now. Would be the better choice than migrating from SXOS as these tutorials often are bad.
