The latest version (.55 as of today) is being flagged by Windows as a trojan.
Copy pasting from my other response. But either way it was reported that v0.56.1 doesn't have the issue, so you can try that out.
From my other post: To be absolutely certain and treat this seriously, I ran the previous version (v0.55) as well as v0.56 through VirusTotal, an anti-virus scanner.
On VirusTotal, 0 out of 62 security vendors have flagged anything malicious, so it appears to be a false positive flagged by Microsoft Defender. Attached the results below:
A player also very helpfully dig some digging for me and sent me this from reddit which I will also attach here:
TLDR:
It’s a false positive triggered by Defender’s AI pattern matching, not a confirmed infection.

Hi there, I've already verified this with VirusTotal, you can check the other comment - it is a false positive by Windows Defender and you can google the exact error itself or check reddit threads that confirm that it is a false positive.
As for price tag, this was already explained in a previous announcement as well as a comment here. The game is moving onto Steam so I wanted to temporarily disable new purchases while allowing older users who had purchased the game to continue get access to updates - I have sent an email to itch.io to do this but there hasn't been a response in two days so for now the less elegant solution is to set it to a maximum price to prevent that.
