I had console app and wanted to try to wrap it into compose desktop. I did it. On Linux it work as expected. I launched it from Intellij Idea on windows virtual machine and it worked to. But when i built it (tried both: msi and exe) it simple do nothing when i try run blocking operations, where RxJava is using. In these places i try to download data from internet (retrofit) and put in into SQLite db (exposed). Looks like operations just hang.
