Did you attach your log file?

No, I could not find a log file at {Game_Directory}\MelonLoader\Latest.log

If you've got that message, you've got a log. We'll need it to do anything more with this.

Update to MelonLoader 0.6.6, that has the fix, and that is the version the BTD6 modding communities are using.
