No using analyzers' results

[yangtt57]

Hi, I just use Ghidra load the binary file and dont use any analyzers, in gui I got this result, which almost has anything, couldn't get the assembly and CFG.

But I can iterate the asm instructions of a function using script api(even could get the highlevel pcode!), and later build a control flow graph, like this:

what caused this? could anyone explain:)
