...without error message , loading screen or even lags, i right click and within a few miliseconds im on my desktop, happened for the third time now, seems like that bug was triggered by the same action, as far as i can say in my case
check if your gui_manager.xml has set to true the catchexception value. In the past this worked for me when remote crafting was introduced. Somehow i had it set to false and everytime i pressed the crafting icon the game client would crash.
You moved my message but my game ONLY crashes when I right click on potions, everything else I can right click on.
Issue is related I just tried to replicate the issue, i can right click fine a few times on blank slot, potion in slot, spell in slot, melee ability in slot and suddenly i crash on just a blank slot i already tried on if you are on discord and you crash to any right clicking in the hotbar then please send overseer bot your client_1.log file before you login again and state its a logfile after a hotbar crash
