For external links you need to disable oembed discovery:

add_filter('bp_embed_oembed_discover', '__return_false');

For internal links, you need to prevent oembed from bypassing oembed discovery:

add_filter('oembed_request_post_id', '__return_false');

The error seems to be back, uploading any photo under 452px causes the issue.

The solution suggested by @dragoeco seems to work:

define( ‘BP_AVATAR_ORIGINAL_MAX_WIDTH’, 150 );

My installation uses the docker image: wordpress:php7.4-fpm-alpine

My environment:

PHP: 7.4.13
WordPress: 5.7.1
BuddyPress: 7.3.0
GD: bundled (2.1.0 compatible)
Imagemagick:3.4.4

Plugins enabled:

BuddyPress: 7.3.0

Theme:

Twenty Twenty-One: 1.2

2020 is still interested in finding out this, would be great if someone could bring some light to the issue.
