I have tried using MultiMC but the result stays the same, I have also installed the latest java version but that did not help either.
Below is the error after I updated java and used MultiMC. (Minecraft starts fine if i remove Fabric API but i obviously need that.)

Not a fabric issue:

Mixin apply for mod flytre_lib failed flytre_lib.mixins.json:base.MiningToolItemAccessor -> net.minecraft.class_1766: org.spongepowered.asm.mixin.gen.throwables.InvalidAccessorException 
No candidates were found matching field_7941:Lnet/minecraft/class_3494; in net/minecraft/class_1766 
for flytre_lib.mixins.json:base.MiningToolItemAccessor-[FIELD_GETTER]::getEffectiveBlocks()Lnet/minecraft/class_3494;

You don't say what version of Minecraft you are using,
but that field was changed from a Tag/class_3494 to a TagKey/class_6862 in 1.18.2
https://github.com/FabricMC/yarn/blob/1.18.2/mappings/net/minecraft/item/MiningToolItem.mapping

Looks like flyte-lib is still using the 1.18.1 code in its "1.18-2" version
https://github.com/Flytre/FlytreLib/blob/1.18-2/Common/src/main/java/net/flytre/flytre_lib/mixin/base/MiningToolItemAccessor.java

Thank you so much! I found some more issues but i was able to figure it out on my own.
