View source for Once again about an empty screen

Hi all !
I have tried to install Wacko for testing and received an empty screen.  I read here about such problems, but I did not see the solution to my issue.
The whole set looks like this -
Windows10 + latest XAMPP 8.2.12 (Apache/2.4.58 (Win64) , PHP/8.2.12, 10.4.32-MARIADB) + Wacko 6.1.25 = empty screen.
Next, I try to install versions lower and get 6.1.3  works successfully. Then I try upgrade it to 6.1.4 and I get an empty screen again. The same empty screen is obtained by fresh installation 6.1.4.
Is it possible to rise to 6.1.25 (and go on) in this configuration?
Thanks.
