I have survived all updates but 7.1.5 -> 7.2.2 killed my instance

I erronously fixed the double quotes (adding one before the closing parenthesis).
Now I have in my logs:

Hi,
Now, I am on 7.3.2 with same problem. I have removed the MIGRATION file then recreated it manually giving own to apache on it and its parent folder. My log is here after, still can't go past the connexion screen. I would like to start using ProjeQtor with my collegues from the beginning of the next year. Should I get rid of this installation and start a new one ? Should I throw postgresql and go with mariadb ? Here after my log:

Hi,
I am always taken back to the login screen. I can't go past it as is shown in this video www.useloom.com/share/48e1d3da1fba45f0baa9ed482d6e9c8e
