Starting Publisher version 1.10.0 i create a new document and got the info, that there is an update to 1.10.1 available. I still had the document open and starting downloading and installing the update. I saved the document but didn't close it. The download was done and install the new version. Publisher was closed. Then I try to start Publisher and got the message „You can not open 'Affinity Publisher.app' because it's damaged or not complete.“ (in german: Du kannst das Programm „Affinity Publisher.app“ nicht öffnen, da es möglicherweise beschädigt oder unvollständig ist.)
The app-icon of Affinity Publisher is also lost. I installed the first version 1.8.6. But it doesn't start with the same crash info and the app-icon is lost even in the dmg-file.
I'm working under macOS 10.12.6 and Affinity Designer (1.101) and Affinity Photo (1.10.1) are on this machine and still work fine.
Maybe it's a problem only on my machine. I tried to solve the problem with starting in safe mode and with first help in the disk utility in recovery mode. The crash still exist. Publisher doesn't start.
