anybody ???

I let mine site over night i woke up this morning to the same big blue box but no error its wired to say the least, it did work after initial update to 1903 but now it seems like it don't work very strange, and i wish someone had a clue as to how to fix it.

OK so i went digging and besides that other error up there i have this as well , i begin to wonder if MS really tested this or not here is the other error i got. only virtual stuff i been using is the new sandbox or trying too, should i do what it says ?? @Brink can you please chime in here?.
