After the last update of Fluent Forms the integration switched off

From previous post:

After the last update of Fluent Forms the integration switched off and it is impossible to switch on. Does not work anymore.

Follow-up: also it is impossible to install Fluent Forms PDF Generator (after complete uninstall) – from the Fluent Forms integrations panel. Please, help, I admire your products most of all!

My php version is php8.3-fpm. What happens? After the update of the Fluent Forms at the integrations panel (Fluent Forms PDF Generator) I saw the button Install. I has it installed yesterday and it worked. But today I saw it not activated in the list of plugins. So I uninstalled it, installed it again (latest verion 1.1.11), but upon activation – I again saw it non-active in the list of plugins. morever – the clicking on the activate button in the list of plugins just reloaded the page with plugins list. No error in the error log, only two small details I noticed:

1. No subsequent Fonts instalation was required of me.
2. Fonts like DejaVu etc. were not in the vendor’s folder, neither in Fonts, neither in ttfonts dir. But I had no error about that in the php error log.

However, on 30th of November, when Fluent Forms PDF Generator worked (version 1.1.10) I had this:

You might think that if I install the version 1.1.10 – it would work? No. The same situation. Also manually adding the fonts to the corresponding /wp-content/plugins/fluentforms-pdf/vendor/mpdf/mpdf/src/Fonts/ folder or even ttfonts folder manually created – did not solve the issue.

I am at a loss why the 5.1.8 update of the Fluent Forms caused this inability to have functioning previosly installed fluentforms-pdf plugin. And do not know how to wipe it clean so I can installed it again – believe me I tried for 3 hours this morning.
