Something on your system, most likely a security program/antivirus of some kind is preventing calibre from creating a worker process to display file dialogs. You can work around it by setting the environment variable CALIBRE_NO_NATIVE_FILEDIALOGS to 1.

See https://manual.calibre-ebook.com/cus...ment-variables

for how to set anvironmnet variables.
