I'm having difficulty reproducing this.

Does this same environment work fine with a supported browser?

Also, was your installation in/accessible via a subfolder URL by chance (i.e https://domain.com/nextcloud versus https://nextcloud.domain.com)? That can make a difference.

Since you you didn't provide one in your report, I have to ask: is your config modified in any way or - better yet - can you provide it?

Does this same environment work fine with a supported browser? => YES

lso, was your installation in/accessible via a subfolder URL by chance (i.e https://domain.com/nextcloud versus https://nextcloud.domain.com)? That can make a difference. => I have 2 Nextcloud installation with same issue. => Install number 1 is redirected to https://domain.fr/nextcloud/index.php/nextcloud/index.php/apps/dashboard/ (because nextcloud access from subfolder => Install number 2 is redirected to https://domain.fr/index.php/index.php/apps/dashboard/ => So with subfolder or root install it's the same.

is your config modified in any way or - better yet - can you provide it? => Default configuration. But one upgrade from an 23 install and the other is upgrades from a lot of years, first install was Owncloud 6. But all upgrade are only Major to Major+1.
