No problem at all, thanks for your screenshots! It's strange that no Affinity related folders appear under Containers, however I can see in Group Containers there is a folder titled '6LVTQB9699.com.seriflabs'

Hi @Dan C here are the screenshots. Under seriflabs folder, the appinfo folder is empty.  Can't expand it to show anything.  But under seriflabs.beta, the appinfo folder can be expanded.

Apologies for the delayed response here!

@v_kyr & @R C-R -

This was the location I used to provide, however I have all 3 apps installed from the Mac App Store (as newly downloaded since installing Big Sur) and my appdata is all found within;

~/Library/Containers/[Affinity Photo/Designer/Publisher]/Data/Library/Application Support/

I will do my best to get clarification on this, as I believe this is where the app data from the Mac App Store can now be found for the Affinity apps.

@Immary

Many thanks for the screenshot provided - this is certainly strange, however it may indicate that the app has never launched 'far enough' to generate these files. I am currently awaiting some further steps to attempt here, my sincerest apologies for any inconveniences caused here.

Maybe this is a change related to Big Sur? I am still running Catalina & like with all previous macOS versions I have used, the Affinity apps I have purchased from the MAS use the "com.seriflabs" Container style folder pathnames, the same style as used with the many "com.apple" folders in ~/Library/Containers/.

Thanks R C-R, I can confirm this is a Big Sur change, and we've updated our FAQ here to match - 

Any users on Big Sur should see 'Affinity Photo' etc in place of 'com.seriflabs.affinityphoto', hope this helps clear this up

@Immary thanks for your continued patience here.

I suspect that these files aren't being generated on your Mac as the app isn't able to initialise far enough into the process to begin writing these files.

As far as your crash report shows, (which is rather 'light' on data, which would also backup the above claim), this is the CODESINGING error which many users are experiencing on High Sierra, for both Affinity and other third party applications, as can be seen here -

Unfortunately as it stands, we can only suggests actions to resolve this, until Apple can provide all users with a fix. Unfortunately I do not have any other suggestions here currently, so I recommend contacting Apple support directly - making it very clear to them that this affects more than just the Affinity apps, and the app developers cannot repair this issue.

From what we understand, it was the following security update that broke this for many users, although we haven't been able to confirm this 100% yet. https://support.apple.com/HT211946

Of course I will do my best to update this thread with any new information we get regarding this issue, my sincerest apologies for any inconveniences caused in the meantime.

Hi @Dan C thank you so much for all the suggestions and explanation given so far. I've learned new things from the experience and gain some understanding also. In a way, I feel some trouble have been lifted now that I know the error is due to my current OS and not the app.  That knowledge alone helps a great deal.  I wish you the best and commend you for your patience and dedication .
