I recently upgraded to Catalina 10.15.3 from Mojave. Since then, I've noticed that after the computer has been running for a while, apps won't launch from the toolbar. They just start bouncing, but never come up. Restarting the computer fixes the problem, for a while. Anybody find a fix for this?
This is on a 2019 MacBookPro 15".

Uninstall Sophos as per the developers instructions. No Anti-Virus software or so-called “cleaning” apps are needed or recommended for Mac OS. They can conflict with Mac's own built-in security. At best they will slow your Mac by using unnecessary resources and at worst will bork your entire system. Your Mac has all the built-in protection you need.

After that run another Etrrecheck report. I wouldn't be surprised if that was your issue with Gatekeeper.

Boot into Safe Mode (Use Safe Mode to isoloate issues with your Mac and Playing Safe: what does Safe Mode do?) and then reboot normally. Test to see if the problem persists.
NOTE: Safe Mode boot can take up to 10 minutes as it's doing some system cache cleaning, volume verifying and directory repairing.
It DOES also happen when apps are launched (or attempted to be launched) from the Finder. It looks like, from the logs, I've got two warring versions of GateKeeper. One running from /System/Library either Frameworks or PrivateFrameworks, and the other running from /usr/libexec/syspolicyd. I wonder if Mojave wasn't properly cleaned up on the Catalina 10.15.3 install.
I'm noticing the problem with non-Apple apps and the Backblaze Preference Panel, though not until the machine has been running a while. (Problem apps: 1Password, Google Chrome, VMWare Fusion, BBEddit)
Oh, and EtreCheck!
Yes, it still happens in Safe Mode. The log snippet I posted seemed to show ambiguous linking of security-related classes, and the app-strangling seems like the kind of thing an Evil GateKeeper™ could do. I am attaching an EtreCheck report.
I'm thinking that my best (albeit terrible) recourse would be a clean Catalina install.
It sounds like it may be a problem with low application memory, have you seen any messages about that?
But rather than guessing you can post an Etrecheck reort.
It is a diagnostic tool that's very useful to us in finding problems. Also it will give us further specs on your Mac. After it runs post the log file here. It will contain no personal information. Allowing full drive access will improve the quality of the report.
To post the log file click on share report and use the Additional Text icon in your reply window.
I'll post a log the next time that I'm at my Mac. I'll also try launching apps directly from the Finder. The MBP has 64GB RAM, though, and very little was running, so I don't think that it was a memory issue.
I'm not on Mojave so I can't be sure but I find nothing in the first file path you posted related to Gatekeeper. I wouldn't mess with syspolicyd as it has lot more functions than just Gatekeeper.

Have you tested in Safe Mode as Old Toad suggested?
Just a single line, since you may have not seen my Log Snippet earlier... I attached it a few minutes after the inital post.
Feb 20 14:12:48 Johns-MacBook-Pro-2019 syspolicyd[678]: objc[678]: Class PolicyScanCacheTarget is implemented in both /System/Library/PrivateFrameworks/SystemPolicy.framework/Versions/A/SystemPolicy and /usr/libexec/syspolicyd. One of the two will be used. Which one is undefined.
Aslo, do see the same behavior if you launch the apps from your Applications folder?
Yup 64GB RAM should be enough, unless you're doing something very extraordinary! I'll keep an eye out for your log.
The issue still arises in Safe Mode. As I mentioned elsewhere, I am theorizing that it is a GateKeeper malfunction. I may need to clean install. Sigh.
Uninstall sophos.
Problem still occurs in Safe Mode when Sophos isn't running. But I will try this anyway.
I believe that this has fixed my issue. Thank you for your help.
You're welcome, glad it's sorted!
