Crash report / bug report: incompatibility between Citrix Workspace & Canon EOS Webcam Util on MacOS

[JediNick23]

Took me awhile to troubleshoot why Citrix Workspace-based apps on my employer's MacBook were all unable to open & would either fail silently or throw a crash report.  But eventually was able to determine that the at-fault interaction was Canon EOS Webcam Utility and Citrix Workspace (successor to & backwards compatible with Citrix Receiver) not playing nicely with each other *at all*.  Uninstalling Canon EOS Webcam Utility and rebooting the MacBook completely resolved the inability to open Citrix Workspace apps.  Copy-pasting first couple hundred lines of crash report below; I'd give more but this forum limits messages to 20 thousand chars.

I'd love to submit a similar bug report submission to Citrix' support team in case it's more their fault than Canon's. But their website looks like they'd have me jump through more hoops trying to make an account with them.  Am hoping Canon software engineers can either get in contact with them directly, or someone can respond here to let me know an easier way for me to reach them & share error logs like this.

Hello John_Q,

i have the same issue and after any search, i have found this post.

I have on MacBook Pro M1 the citrix workspace 23.09.0.4 and after installing the EOS Webcam Util Pro Version 2.30 i have in first time see no problem.

But if i try to open an App/Desktop via Citrix workspace, the citrix client crashes with an execution error.

After Exiting the Citrix app, uninstall the EOS WebCam Pro Utility and restart the Citrix workspace Client. Now the App/Desktop in client don't crahing anymore.

Give it a solution / fix fir that failure?

Thanks and regards,

Sascha

By now I've upgraded to macOS Sonoma 14.2.1

Do you know where this bug report is in the software engineers' backlog, and whether it's been resolved as of Citrix Workspace Version: 23.11.0.67 (2311) ?
