how do I delete Java update 281? 

 

[Technic Launcher doesn't open any mods]

Right so I have a Macbook Pro Big Sur, and whenever I want to open a modpack on the Technic Launcher the modpack icon pops up for a few seconds, and then closes. I have Java 8 update 281 (viewed in the Java Controll Panel) so I don't really know what the issue is. Any help? 

[All modpacks crash upon opening MAC]

Right lads, I'm trying to play some modpacks on my Macbook, they download just fine. But when I try to open a modpack it crashes immediately & says ''MODPACK QUIT UNEXPECTEDLY'' 

My MacOS version is Big Sur, I have Java 8 update 271, I have no idea what kinda specs you folks need to help me this is the first time I'm posting something here.
