Package problems

Hi i started with Unreal a week ago and made a tutorial (https://youtu.be/arqkJEdLmCs?si=BQTnuEUmufM3AzE6), i didn’t finish it yet (i have to start the chapter 12) but i wanted to export the project.
The first time that i tried give me some errors and couldnt do it, them i fixed some and could export with two errors remaining but when i press the buttons to change the cameras the program brokes and the cameras show planes that shouldnt.
This are the two errors, the second one is repeted at least 8 times:
PackagingResults: Error: Invalid Bytecode: Interpolation mode for PS input position must be linear_noperspective_centroid or linear_noperspective_sample when outputting oDepthGE or oDepthLE and not running at sample frequency (which is forced by inputting SV_SampleIndex or declaring an input linear_sample or linear_noperspective_sample).
PackagingResults: Error: source component 0 in temp r2 not initialized. Opcode #54 (count is 1-based)

I couldnt find something to fix it and dont know what to do.
Thanks for your helping
