    I get this error if I try to use no exceptions. The unity manual says i should use none for best performance.
    Unity 2020 LTS


    26.3.loader.js:1 exception thrown: undefined - Exception catching is disabled, this exception cannot be caught. Compile with -s DISABLE_EXCEPTION_CATCHING=0 or DISABLE_EXCEPTION_CATCHING=2 to catch.
    printErr @ 26.3.loader.js:1
    systemlords.26horses.com/:1 Uncaught (in promise) undefined - Exception catching is disabled, this exception cannot be caught. Compile with -s DISABLE_EXCEPTION_CATCHING=0 or DISABLE_EXCEPTION_CATCHING=2 to catch.

    @Shadowing Did you ever find out the root cause? I have the same problem.

    I have a theory. If there is no exceptions then if there is any error at all it won't handle it properly. Including even game engine bugs. So i was thinking in order for no exceptions to work is there has to be no bugs what so ever. Other wise all code gets halted.

    but idk lol.

    So I just been leaving exceptions on. Performance seems good. Its better performance than what I get on mobile.

    If i change Enable Exceptions to None. I get these errors. in Unity 2020.3.21
    I'll see about testing on 2021


    Uncaught undefined - Exception catching is disabled, this exception cannot be caught. Compile with -s DISABLE_EXCEPTION_CATCHING=0 or DISABLE_EXCEPTION_CATCHING=2 to catch.
