Original GitHub issue: https://github.com/debauchee/barrier/issues/1555

What happened?

I have a mac client (with ssl disabled) connecting to a windows server (with ssl disabled) and the the mac errors with this error.

**Assertion failed: ([NSThread isMainThread]), function _NSPersistentUIApplicationExplicitlySupportsSecureCoding, file NSPersistentUI.m, line 269.**

I don't have the issue if I set the server to Enable SSL but turn off "require client certificate"
I don't usually have this issue so not sure why this is happening.

Version

v2.4.0

Git commit hash (if applicable)

3e0d758b

If applicable, where did you install Barrier from?

Still happening, also happens with Synergy Pro
Its intermittent but when it happens its fairly consistent with random working spikes.
This happens even if the server is not running.
It also happens from a rosetta terminal
Still errors wth crypto enabled.

$ ./barrierc -f 192.168.x.x

Quick hint:

Seems to be related to synergy etc having 2 processes running, so the thread check realises it's not the only thread and gets caught up in a reset loop.
