Issue SMAPI crashes instantly

[Catomax26]

Note: I am using the GOG version of Stardew Valley.

For some reason when i updated to 1.5.6, SMAPI refuses to open (SMAPI 3.16). In an older version of Stardew Valley (1.5.4, SMAPI 3.12) it opened and loaded mods normally.

Why does this happen? I installed everything properly.
