Invoiceninja 5.x blank page (after trying to disable secret)

[ralphGL]

What type of hardware are you using: Old laptop or computer
What YunoHost version are you running: 11.3.0.2
What app is this about: InvoiceNinja

Describe your issue

InvoiceNinja 5.10.55~ynh1 worked fine for more than 8 months until a few days ago on my debian 11 system. Then I tried to disable login secret, as described in Disable "Secret(optional)" the right way - Self-Hosted | v5 - Support Forum
But after this I get only a blank page after accessing to my invoiceninja installation.
So I tried to undo my changes in .env and in /etc/yunohost/apps/invoiceninja5/settings.yml and run “php8.3 artisan optimize” and restarted nginx. I also tried to clear the cache with “php8.3 artisan cache:clear”.
But there is furthermore only a blank page.
I would be very grateful for any helpful tips. I would be very reluctant to try to restore the last backup, firstly because some bookings were made afterwards and also because I fear that this might not solve the problem.

Which line exactly did you delete in the .env file?
I had no pb on the same version : I just commented the API_SECRET one (not the one from settings.yml a this is useless) and then run php artisan optimize and it worked.
