I have a text trace of the code of the real work of the library, but IDA at the address where the code should be shows that there is data, calling the "convert to instruction" function gives the wrong code, how to make IDA show the same code as in the trace?
this is real code trace:

this is what ida shows:

Cutter works good and shows the same code, as in debugger, but how to configure IDA to show the same?
