Heidisql crashes when I am loading SQL script

Hi! When I am loading the SQL script that creates the training database ("demo-small") from Postgres Pro website, the script freezes at query 131. So, the whole system freezes, then the screen fades off and a bit later my laptop reloads Windows. The database I am trying to load is not that big (99mb). I am using the latest build 11.0.0.5919 on Windows 10. Tried to run the same sql file using Heidi on more powerful PC - the result is still the same. When I am using psql command line, the database works just fine. Any clues why it's happening or how to fix it? Thank you.

Try not to load, just run it. There is an option somewhere for that.

There is also a new release, and already several new nightly builds. Please update and retry.

The "Run" option mentioned by BubikolRamios is in "File" > "Run SQL file".
