have you any other child-theme files than the normal starting set ( functions.php, style.css, screenshort.png ). F.e. an own header.php or some edited alb elements in a child-theme shortcodes folder?
Secure them by ftp and try the new enfold without those additional files. The update from 3.6 to 4.5 is a big step. There are a few major updates in between, so that even core files like header.php could have some changes.

And please in the future :

“I updated the theme by deleting the old one (3.6) and updated to 4.5 …”

why not rename the old enfold ( f.e. to enfold-old) and then upload the new one (4.5) – because if you got these troubles like now you can always rollback to the old version which has been running well.

i will delete the background-images if you see it.

on the most of the developer tools each modern Browser got- we can influence the coordinate points and move them as you like – afterwards you can copy the css code. ( on firefox we can not shift to 100% point – so that had to be manually corrected then ):

i reopened my test-page on : https://webers-testseite.de/elegant/polygones/
i will close it soon on various reasons.

By the way the same is on Safari – Unfortunately this is a setting in the Safari Options. – You have no influence from the source code of your site on that.

just change the code to:

add_filter( 'avia_post_nav_entries', 'enfold_customization_postnav', 10, 2); 
function enfold_customization_postnav($entries, $settings)
{
	if($settings['type'] == 'portfolio')
	{
		$settings['same_category'] = true;

		$entries['prev'] = get_previous_post($settings['same_category'], $settings['excluded_terms'], $settings['taxonomy']);
		$entries['next'] = get_next_post($settings['same_category'], $settings['excluded_terms'], $settings['taxonomy']);
	}

    return $entries;
}

what do you mean by “showing incorrectly” – i see this :

You put it in the functions.php of your parent theme at the very last entry

you can try it after the place where this is listed:

/*
 *  register custom functions that are not related to the framework but necessary for the theme to run
 */

but – as said before these entries are definitly lost on next enfold update.
On editing such important files – please be sure you got ftp access – to make a rollback if needed.
a missing semicolon or wrong Quotation Marks and you can not edit it via dashboard ( because white screen of death).

i got this yesterday too – allthough i have my billing information allready set for the api, they have to be renewed – because of some changings.
After that all works as before.
So accept and renew billing information on google

If you got that error log with the retired version you can do this to child-theme functions.php til next Enfold update

function avia_maps_version_number( $api_src ){
    $api_src['version'] = '3.34';
    return $api_src;
}
add_filter( 'avf_google_maps_source', 'avia_maps_version_number', 10, 1);

by the way i would like to know a child-theme solution for that here: https://kriesi.at/support/topic/change-color-palette/#post-1016276

to have a second row f.e. with colors i like and do often use on my installations.

on avia-modal.js i can see on line 389ff this $.AviaModal.register_callback.modal_load_colorpicker = function()
but how to add a second palettes row over child-theme functions.php

i do not know the other codes – i use it – when i need it:

if(!function_exists('avia_debugging_info')){
  function avia_debugging_info() {
    // 
  }
}

is that obsolete? – No it still works – tested it few minutes ago (refresh all caches and merging in Enfold)

you can get rid of every function or overwrite it in your child-theme functions.php when it starts in original source code with:
if(!function_exists('…'))

by the way there was a filter to rename the Theme and child-theme :

/** All of the Styling options you set in the theme’s Styling options get saved to a file in your uploads folder / dynamic_avia called enfold.css.
If you have changed the theme name or something like that you may want to re-name this file to better reflect your own branding ( :LOL dear Brand). You can use the following function to do just that: */

add_filter('avia_dyn_stylesheet_file_path', 'avia_change_filename');
function avia_change_filename($stylesheet){
return 'myfilename.css';
}

___________ offtopic ___________
So – I don’t mind that my customers know which WordPress theme I’m using. On the contrary, a theme that is so well distributed and has a strong community is more of a good selling point.
Of course, if you want to present the beautiful styles and layout possibilities as your own achievements, branding is a hindrance.
For my part, I recognize an enfold page even without branding at first glance in the source code. The classes and IDs are so clear that you have to invest a lot of work to obfuscate a topic there.
