When i remove mods from the palyset there is no problem. Also i did your recommendations but it didn't work I can play vanilla but can not playin with an mods.If you remove the mod from the playset, is it then still listed in the all installed mods section and does it have an error message there? Does the reload button in that section help? If not, does it help if you delete dlc_load.json and launcher-v2.sqlite from the eu4 folder in Documents?
