Bug after 1.4.0 (makes game unplayable)

[Finch4990]

After updating to 1.4.0, I become stuck at the "launch mode" screen when booting up the game and am unable to progress any further than this as the game refuses to register when I click to play online. Not an issue on previous versions of LLL, not an issue without LLL.

Providing logs (LogOutput.log) when this happens may help troubleshoot where it went wrong exactly.

I've noticed that the game hangs for over a minute now after I try to click Online Mode. Mind you I'm running a heavy modpack based around MoonUnlocks discovery mode with a bunch of moon mods. Totaling just slightly over 4GB, so I've grown used to slow boot times, but this new 1.4 LLL update has added ~70 seconds in my case where assetbundles are "unloaded". Though I'm not sure what this unloading process is supposed to be accomplishing, as my RAM usage remains constant.
Anyway I assume Finch may be closing Lethal Company before LLL finishes its new boot process. Whatever was changed between 1.3.13 and 1.4 has added significant loadtime during the "AssetBundle Unloaded (XX.Xs)" step. If I try to click again on Online Mode during this hang windows intervenes and claims Lethal Company has stopped responding. I expect many users will conclude something has crashed.
On my end I'm reverting back to 1.3.13 until what exactly this new boot process is supposed to be accomplishing is clarified.
