Ive installed windows 10 using bootcamp assistant on my macbook pro late 2013. I got installed macos ventura via open core legacy patcher. After windows installation I tried to switch back to macos but all I got is startup error. Is there any way to restore this files? Here is error photo

That's not really an error, per se. It is simply reporting that your macOS system is either incorrectly installed, or reporting that some part of the system boot is missing, or corrupted.
You just installed Windows, and the Windows boot setup likely "messed" with the macOS boot files.
Reinstalling with your OCLP installer should fix that.

So, you erased the USB stick, the one that you used for the OCLP install, so you could use that stick to install Windows?

Just a tip - If you set up a special installer, so you can use a macOS system too new for your older Mac, it's good idea to keep that installer, just in case you need it again. Set up a Windows installer on its own USB stick.

I don't know how you could re-make that OCLP installer in Windows. Easiest would be to do that on another Mac.
