I tried to solve the problem related to the archive, but changing the buffer size and rewriting the class did not bring the desired result. At the same time, I made sure that the archive itself is not damaged, and the cause of the problem should be found elsewhere. It may be worth paying attention to other parameters or functions that may affect the work with the archive.
the code was moved to the Zip4j library. the problem has disappeared
