I don’t know if you tried it or not, but I’d suggest that you install the latest release from their Download Page, as opposed to other sources.
I’ve noticed on Android, that the F-Droid Version is not “quickly” updated and frequently breaks due to breaking changes from Google.
(I’ve also just upgraded to v4.0 on my android phone and it’s working - good luck!)
I’m sorry this happened, but it seems rather reckless of the author to be running “Malicious PoCs” on their “daily driver” (re: the PC they use for everything).
If I was in the habit of running “Malicious PoCs”, you can be certain it would be isolated from the rest of my system. This could be in a sandbox or a vm. Heck, just created a dedicated (one time use) “new user” would have been better than "Hey, let me just download and run some random shell script. Oh, it needs root? No problem!
