Deprecated: trim(): Passing null to parameter #1 ($string) of type string is dep

Same error here, the error happens in \wp-content\plugins\translatepress-multilingual\includes\class-url-converter.php Line 784 if $abs_home is not ending with a trailing slash.

If you are familiar with code you can replace Line 784 in class-url-converter.php:
Replace this
$home_path = trim( parse_url( $abs_home, PHP_URL_PATH ), '/' );
with
$home_path = trim( parse_url( $abs_home . '/', PHP_URL_PATH ), '/' );

if not downgrading might be a fast fix:

if you scroll all the way down you find:
Please select a specific version to download.

Select the version and there you go! ??
