Filing mostly in case anyone else hits this and is looking for workarounds:

Since the Update to 24.04 PHPStorm crashes on open for me. I think when it tries to preview a markdown file, like a README.md which is shown when opening a project.

```
[0309/094602.913394:FATAL:setuid_sandbox_host.cc(158)] The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I'm aborting now. You need to make sure that /home/user/bin/phpstorm/jbr/lib/chrome-sandbox is owned by root and has mode 4755.
```

Workaround 1 (wont persist reboots, needs root):

sudo sysctl -w kernel.apparmor_restrict_unprivileged_unconfined=0
sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=0

Workaround 2 (persists and doesn't need root):

* Run `<path-to-phpstorm>/bin/phpstorm.sh dontReopenProjects` (to avoid it crashing on start)
* ctrl+shift+a
* type "Registry..."
* disable the "ide.browser.jcef.sandbox.enable" option
* Restart phpstorm
