Thanks for your message.
The error message "No plugin to handle acsm" is because the plugin crashed during execution for some reason, and apparently Calibre thinks that's the same as no plugin being present.
Now the question is, why does it crash..
The log you posted states that the plugin was unable to decrypt the user certificate using the adobe device key - which is something I've never seen before, unless I was manually messing with stuff.
When you go into the plugin settings, does it correctly state "Authorized with ADE ID
xxx@example.com on device xxx emulating ADE xxx"? Or does it say anything about a corrupted authorization?
You said it's configured to use "the imported Adobe credentials" - did you click "Link to ADE account" and entered your Adobe credentials, or did you click "Import activation from ADE" and imported an existing activation from ADE (running through Wine)? Or did you import a ZIP file from another Calibre installation?
Fedora 35 does not yet have OpenSSL3, so it's not the same bug / similar bug as in Ubuntu 22.04...
Can you try clicking on "Export account activation data", save the resulting ZIP file somewhere, open it, and check if there's a file "devicesalt" with a size of 16 bytes in there?
