Kasts on Windows

Hello all. Hoping someone can help or point me in the right direction.
I downloaded and installed Windows version of Kasts app on Windows 11. I know the Windows builds are supposed to be for testing only, however I downloaded what was labeled as stable build (from here - Kasts_Release_win64 [Jenkins]). It worked for the first 5 minutes after launching; allowed me to connect to Nextcloud Sync and began syncing the podcasts; then it crashed, and since then when I launch it it stays minimized in the taskbar. Reinstalling did not help. What can I do to get it working, or where to get help?
