wp-admin javascript issues after update to 5.3.2

[pegla]

Hi,
I believe there's an issue with media-library/theme customizer specifically with 2 files on lines (I turned on script debugger and these are unminified files):

- line 207 in media-audiovideo.js
Uncaught TypeError: wp.media.collection is not a constructor

wp.media.playlist = new wp.media.collection({

- line 602 in media-grid.js

Uncaught TypeError: Cannot read property ‘extend’ of undefined

Details = EditImage.extend(/** @lends wp.media.view.EditImage.Details.prototype */{
// ....

I initially thought this as theme error or server error but my guys from Mochahost said all is good on their end specially since this is Javascript error. And I did fresh wordpress install and update - 0 plugins 0 themes it still happens. Also tried different browsers, Firefox, IE, Edge and Chrome...

I tried some javascript hacking did some workarounds - but none of it worth mentioning - except from debugging I found out that:
'collection' doesn't exist on wp.media at all and even when I wrapped it in setTimeout for few seconds it's still wasn't there. I also tried accessing objects directly from window.wp.media/window.wp.media.view.EditImage -> no luck there
I'm not good with backbone and these files are webpack build so it's bit hard to figure out what's wrong.

I filed a support questions here:

​https://wordpress.org/support/topic/wordpress-5-3-2-javascript-errors/

I'm using PHP 7.3 and I tried with 5.6 same thing happens - fix for now would be to downgrade to WordPress 5.2.5 where it also happens but media library and appearance/customizer seem to work fine with this error:
Uncaught TypeError: wp.media.collection is not a constructor

Main issue is that this is happening when I update my websites - and it's on all of them. I usually build wordpress sites and when I give access to admin to clients they update wordpress to get latest security updates - I now need to tell them not to update and if they do update I will need to revert back versions and hopefully they won't break anything.

Anyone interested I can share more details or access for the site to check it up.

Thanks,

backend error on second site - no plugins - no themes - basic stuff only - fresh installation

[pegla]

error on customizer - no custom themes - no plugins

[pegla]

First site error found on empty customizer - errors are same as on the luck project .png file

this is with wp_bakery plugin from where you can't access media library - same error plus one more I assume derivated from this error. Even if I used /wp-admin/upload.php?mode=list to workaround error on media library this one still apears.

If someone gets this same issue - try asking your hosting to update MYSQL - I didn't realize DB can actually be culprit, sorry for raising bug.
