Hi,

looks like a problem with the integration_deepl app. Can you disable it and check if it helps?

I disabled the integration_deepl app, and now files are being sent normally via Talk.

Although the issue is resolved, I still don’t understand how the DeepL integration could interfere with file transfers in Talk. In any case, it’s not an app I need for my daily use.

Thank you very much for your help — the issue has been resolved.
