Corrupted playback speed!!!

Need help!

Trying to record some voice. I set up my dynamic mic into my Asus Xonar Essence ST. Windows 10 drivers and settings wise everything is working fine. Audacity captures recording and i can hear the playback through my headphones at the same time. In the toolbar i can clearly see the playback speed set at 1. However, after saving the project file and loading it up again, playing it, the record sound so so slow…

What’s going on???

Approximately how much slower than normal?
Slow and low pitched, or slow and normal pitch? Does it also sound crackly or does it sound normal other than the speed?

A short audio sample (just a few seconds) in WAV format may help us to diagnose the problem (see:
