How to recover lost data after resizing APFS partition on macOS High Sierra?

Just now, for installing Linux on the same computer, I tried to resize my system partition (APFS) of MacBook Pro on macOS High Sierra to release enough memory. I used Disk Utility to perform a partition shrink, but the error code 49153 popped up! Now my system hard drive gets completely inaccessible, the worst thing is that I didn't make any backup before. How can I recover lost data after resizing APFS partition on macOS High Sierra? Any recommended data recovery software can help?

In general, APFS resizing error on macOS High Sierra may result from the improper or incomplete partition resizing procedure. No matter what causes APFS resizing error, if we didn't make any backup, we will suffer from annoying data loss issue. Except for unexpected APFS resizing error, mistakenly resizing an APFS partition is also a big threat for data loss issue.

Can we recover data after resizing APFS partition/container on macOS High Sierra?

The answer is "Yes". When we click Partition button, our Mac computer only changes some marks on address table and our lost data still reside on our APFS drive. Even though some APFS resizing errors interrupted the process, it's just because some logical corruptions bother the operating system to locate specific files, the real data still remains physically intact on the APFS drive. Thus, we can recover data after resizing APFS partition/container on macOS High Sierra.
