Hi! We are aware that Cwtch 1.15+ has issues starting on some linux distros due to a library conflict. We believe that has now been fixed as of our most recent nightly (https://build.openprivacy.ca/files/flwtch-2025-02-15-01-08-v1.15.4-9-gb6cb/) which will shortly be released as 1.15.5.
I have activated your account. Please let us know if you have any other issues, or if the nightly fix does not work.
