ttrss no longer listed in applications and trowing admin error but its installed

[baboonandsloth]

running on my onw pc.

I ran system update and updated yunohost but after that Tiny Tiny RSS no longer shows in applications in the admin interface, but the site works and shows up when you click it under domains.

The other weird issue is now when I search for updates or try to remove a domain and I think in some cases other things I am not yet aware of yet, I get this error:
Check for updates
YunoHost encountered an internal error
Really sorry about that.
You should look for help on the forum or the chat to fix the situation, or report the bug on the bugtracker.
The following information might be useful for the person helping you:
Error: "500"

Action: "PUT" /yunohost/api/update/all

Error message:
Corrupted JSON read from /etc/yunohost/apps/ttrss/manifest.json (reason: Expecting value: line 1 column 1 (char 0))

im sure you need more information to help, I just don't know how to do it. Still learning, but if you tell me what to do ill try

I think this is the paste from the log
https://paste.yunohost.org/ugodakates

and this is what it says for the app
