This may be a plugin or theme conflict. Please attempt to disable all plugins, and switch to the default Twenty Twenty-One theme. If the problem goes away, enable them one by one to identify the source of the problem.
If you can install plugins, install Health Check. On the troubleshooting tab, you can click the button to disable all plugins and change the theme for you, while you’re still logged in, without affecting normal visitors to your site.
I tried with Health Check, didn´t help. It disabled all plugins and used the default theme.
So, there is about 2000 menu items. Can this have something to do with PHP limitations? Max variables is set to 5000, time to 120 and memory limit to 2000something.
It seems to load something, because the page gets really “tall”, but it doesn’t display everything. It gets cut from a random point of visible menu items and then the whole browser tab stops working and Chrome asks me if I wan’t to wait or close the page. If I wait for a really long time, it allows me to see the whole menu, but if I touch anything, it hangs up again.
And also, I now have updated to WordPress 5.7 and all plugins are updated to their newest versions with no change to the problem.
Plugins in use:
Advanced AJAX Product Filters for WooCommerce
Akismet
Category Subcategory List Widget
Content Views
Display Categories Widget
GDPR Cookie Consent
Google Analytics for WordPress by MonsterInsights
Jetpack by WordPress.com
More Sorting Options for WooCommerce
Really Simple SSL
WooCommerce
WooCommerce Admin
WooCommerce Remove Product Sorting
WooCommerce Shipping & Tax
WP Fulltext Search Pro
Try to disable plugins one by one. If you can not enter to WP Admin, you can disable plugin by renaming its folder in wp-content/plugins/
for example if you want to disable Akismet, you need to rename
wp-content/plugins/akismet
to
wp-content/plugins/__akismet
This way the plugin gets disabled. You will need to rename them back, however they will become disabled and you also will need to activate them again.
I used Health Check to disable plugins and it didn’t help, so maybe it is not a plugin related issue? PHP server settings? New PHP version (7.4)?
So I’m thinking could it be these PHP variables? I have 2000 menu items, what else counts as a variable? Menu item positioning, various other things? Have no clue, just a guess.
After enabling WP_debug, I got this:
Deprecated: The behavior of unparenthesized expressions containing both '.' and '+'/'-' will change in PHP 8: '+'/'-' will take a higher precedence in /home/u44768/arkisto/public_html/wp-content/plugins/fulltext-search-pro/includes/wpfts_core.php on line 1241 Warning: Cannot modify header information - headers already sent by (output started at /home/u44768/arkisto/public_html/wp-content/plugins/fulltext-search-pro/includes/wpfts_core.php:1241) in /home/u44768/arkisto/public_html/wp-includes/functions.php on line 6362 Warning: Cannot modify header information - headers already sent by (output started at /home/u44768/arkisto/public_html/wp-content/plugins/fulltext-search-pro/includes/wpfts_core.php:1241) in /home/u44768/arkisto/public_html/wp-admin/includes/misc.php on line 1310 Warning: Cannot modify header information - headers already sent by (output started at /home/u44768/arkisto/public_html/wp-content/plugins/fulltext-search-pro/includes/wpfts_core.php:1241) in /home/u44768/arkisto/public_html/wp-admin/admin-header.php on line 9 Warning: session_start(): Cannot start session when headers already sent in /home/u44768/arkisto/public_html/wp-content/plugins/woocommerce-ajax-filters/includes/custom_post.php on line 304
After disabling all plugins and changing to default theme, the errors went away, but the problem persists.

Oh no..
It just seems that the menu is too big. I created a new menu with fewer options and it works just perfectly.
Is this kind of limitation due to server options or power or does it have something to do with WordPress?
Or could it be that some option in the menu is somehow corrupt and breaks it?
I had the same issue, I could add new menu items but instantly after saving the menu they changed into Custom items and the link did not work. I also had other problems, previews of images not working (and hence also the featured images not working) and some loss of Yoast metadata.
This lead me to the wp_postmeta table in the database. It turned out this was corrupted. I have removed all meta_id lines with 0 and with duplicate values. I also made the meta_id a unique identifier and auto-increment, see here for guidance: https://wordpress.stackexchange.com/questions/225641/wordpress-database-lost-auto-increment.
This all worked for me and my menus and images are perfect again.
