As the title say the modpack runs flawlessly in terms on performance, but randomly when i pause the game the game freezes completely and i need to close it with task manager forcefully, this problem is really weird because i think it just happens when i use the fabric mod loader for some reason, when i play fabric modpacks i have this issue but with forge it never happens so i'm out of options, i have tried allocating more ram, lowering settings, and nothing helps

Here's a link from the latest log from ATLauncher https://pastebin.com/iYVh1ACU

So i tried to play and again worked just fine, but now i know somewhat what it's happening i think, when i press pause the game saves, and this crashes the game, for example if i open the chat and i alt+tab outside the game, because the game is not pausing and not saving, then it doesn´t crash, but if i just pause or alt+tab without doing this the game freezes completely, can anyone explain me why? i tried to find some help in the discord server but nobody responded unfortunately, i want to play this modpack and it has been pretty fun until i get this crash that basicalle unables me of playing it, thank you for the time
