Bug: Helper never quits (and stack up)

[loranger]

🐞 bug report

Affected Version(s)

The issue is found in version 4 (4.3 and 4.4)

Is this a regression? (optional)

Yes, the previous versionI used (4.3.2) had the same behaviour

To Reproduce

Steps to reproduce the behavior:

• Start Luban
• Create a project
• Quit (with or without saving, having the project started on SnapMaker or not, it does not matter)
• Monitor your running processes matching Luban

Expected behavior

There should no remaining Luban process running since Luban has been quit, but an helper (for each previously started Luban) is still running and using memory

Sometimes it gets totally mad

[jane-rose]

We confirmed this bug and it will be fixed on next version.

[mutatrum]

I see the same behaviour on Linux, does the fix cover all versions?

[hkarimi456]

Is there a way to clear out the cache or something so that we don't have this memory problem? Thanks

[parachvte]

The issue has been fixed in v4.6.X.
