Very much same here. Went ahead to try to install on FS 2024, began to have an infinite loading screen there. Hopped on back to FS 2020, the very same issue is now present, even after reinstalling, removing WASM and making a temporary empty community folder, all to no avail. The A350 is effectively bricked on me
Edit: it ended up working, after reinstalling inimanager, downloading using alternative downloader, clearing the WASM folder and letting it load for over an hour
