encryption – XLOGGER on Xiaomi?

Installed simply file explorer on my pocket telecreener.

Xiaomi MI 8 Pro, right now it running on unrooted MIUI 12.04

It happens that I have found a .log file, (completly by accident)
with a hundreds of entries, day by day but there are crypted somehow. How can I open and or decode them?

Here is the sample, mostly all look like this:

Any help will be appreciated.
