 This seems to be something that has been occurring for some time without
 resolution in core.

 Just started seeing a lot more reports of it recently for one of my
 plugins, which lead me to dig and see that it has been occurring in the
 same way to other plugins for years.

 Issue: On Plugin Installer page, if you install and activate plugins it
 can show the following message: "The plugin does not have a valid header".

 Most users get around it by going to the All Plugins page and activating
 without issue.

 Plugin that currently seems affected include:
 - Content Control
 - [W3 Total Cache](https://www.pixelwars.org/forums/topic/the-plugin-does-
 not-have-a-valid-header/)
 - [Zapier](https://wordpress.org/support/topic/the-plugin-does-not-have-a
 -valid-header-198/)

 And some from the past few years with same issue:
 - [Etsy Shop](https://wordpress.org/support/topic/the-plugin-does-not-
 have-a-valid-header-150/)
 - [Jotform](https://www.jotform.com/answers/2975729-jotform-wp-plugin-
 plugin-does-not-have-a-valid-header-error)

 That was only what I found on first page of google.
