1. are you using Latte plasmoid in plasma panel? If that is the case then in master version and soon to be released v0.8 this has been fixed
2. the topic was the opposite, when a plasma taskmanager is present in Latte panel it creates crashes but I have just noticed that this has also been fixed in plasma 5.13
