"Cannot read properties of null (reading 'localeCompare')..."

[bigeagle11]

Currently I get the following message when I try to use Patreon Downloader:

"Error handling response: TypeError: Cannot read properties of null (reading 'localeCompare')
at chrome-extension://mnfjhjpninhcccbahcdbcphpifofoajc/src/js/popup.js:124:25
at Array.sort ()
at chrome-extension://mnfjhjpninhcccbahcdbcphpifofoajc/src/js/popup.js:123:11"

For some Post PatreonDownloader is working for some it is not. How can I fix that Problem?
