LogSlate: External Image Picker: DecompressImage failed

my project started and worked fine but after i added some short name versions for keys in the engine code (i allready tried reversing the change) my project it takes 20 to 30 minutes to load and in either vs code or the log i see it repeating this message LogSlate: External Image Picker: DecompressImage failed. the changes i made didnt seem to be cause the message before this one was simple loading and validationg the starter content witch now disabled. the ram usage is also increased by a lot and now takes all the ram i have. i have been through the logs and besides this meesage there is no other error or failed warning. after a while the engine project does start and behaves normal besides the extra ram usage.

i have tried another empty project on the engine and it starts up normal i havent foudn anyone with this issue on the forums or others sources if anyone know how to fix this id be gratefull.

the cause where custom input modifiers that used the imput modifier class as a parent.
