Module cannot be found , npm I —dev-save @types/coinselect

[sheradoo]

My coinselect module was working fine but two days ago it starts telling me module cannot be found , I have tried everything including adding js extensions to the module import , nothing seems to be working, I am using an esm module type in my package.json file , every other module is importing fine including bitcoinjs-lib but only coinselect and please is there any better alternative

please check if I am doing anything wrong I am a new bie
