My Lenovo laptop's settings:
- is plugged in
- no screensaver
- "never" go to sleep/hybernate set to all settings in advanced power options
When music is playing or watching video everything works fine.
But when nothing is happening pc goes to sleep after ~1 min.
Not sure, but it doesn't happen right after restart, only after I begin working.
Here is the system log for sleep event:

How can I solve it?

It is the System unattended sleep timeout setting.
By default it is set to 120 seconds and is hidden.
Setting the registry data Attributes under key
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\238C9FA8-0AAD-41ED-83F4-97BE242C8F20\7bc4a2f9-d8fc-4469-b07b-33eb785aaca0
to value 2 (or 0) makes the option appear in the advanced power settings, under Sleep and can be set to something normal.Source: https://www.tenforums.com/tutorials/72133-add-system-unattended-sleep-timeout-power-options-windows-10-a.html
