My QBs is aborting, H202, H303 and it is not working properly.

Hey, Amcapens.

Let's see if I can help. With H202 errors its essentially a multi-user mode error. You can find the steps necessary to fix this error here. When it comes to an unrecoverable error we can fix this by recreating the steps and finding out which step led to the crash. I recommend reaching out to support. This way they can do a possible screen share and assist with fixing this error. I'm here if you have any other questions.
