site/pages/modules/groups.php

For the error PHP NOTICE [8] Trying to access array offset on value of type int in site/pages/modules/groups.php on line 615 (version: 10.0.29, PHP version: 7.4.1

It looks like a fix may be available. Would it be safe to drop the latest groups.php into either modules or modules_custom ?

Same for sources/activities_submission.php where I supressed an error with ..

function log_newest_activity($id, $timeout = 1000, $force = false)
{
    $file_path = get_custom_file_base() . '/data_custom/latest_activity.txt';

    $old_id = @file_get_contents($file_path);    <-----

Would the newer versions in GitLab be okay to drop into place, or would that blow something up

Yes, both these issues are fixed. Latest files from GitLab should be fine as long as it's from the master branch.
Always overwrite the originals if it is an official fix.
