Same here. Media library hangs (wheel rotates forever), works normal again when I deactivate WP GPX plugin, and hangs again after activating WP GPX.
Also, WP Site Health says,
The REST API did not behave correctly.
The REST API did not process the ‘context’ query parameter correctly.
Problem occurred today for the first time, so I guess it’s related to the new WP GPX release.
