Yes, I did that first on both attempts. Then, before switching back to my microSD card install of Radxa OS, I switched those settings back to ‘Disabled’.
One quick note: I have been using an Anker Nano II 65W USB-C charger, which ran all benchmarks and everything in Radxa OS just fine. But with how the computer resets itself every time I hit ‘Try or Install Ubuntu’, I wonder if that’s what’s throwing things for a loop? Just a potential variable to look at. I don’t have a Radxa 65W USB-C power adapter.
