what is the output when you start delta chat from the terminal?

/Applications/DeltaChat.app/Contents/MacOS/DeltaChat

[Simon-Laux]

Basically your error means that deltachat-rpc-server / deltachat-core could not be started.
But there is not enough information for us to investigate, so please start it from the terminal, maybe there will be additional information.

I just installed Deltachat for the first time and there's this same Error - uncaughtException.
Deltachat version 1.48 , OS Windows10 22H2

[Simon-Laux]

@jincola I need the contents to the logfile. The error for you is a different one, you have ENOENT, OP has EAGAIN.
ENOENT means that the file is not found, but your error message does not show the full path, the log file will.
Also I need to know if your device cpu architecture (32bit/64bit x86/arm)

[Simon-Laux]

What folders are at C:\Users\myname\AppData\Local\Programs\DeltaChat\resources\app.asar.unpacked\node_modules\@deltachat\?

[jincola]

There's only one folder in it "stdio-rpc-server-win32-x64" , and there's a file "package.json" in this "stdio-rpc-server-win32-x64".

{
    "name": "@deltachat/stdio-rpc-server-win32-x64",
    "version": "1.148.7",
    "os": [
        "win32"
    ],
    "cpu": [
        "x64"
    ],
    "main": "deltachat-rpc-server.exe",
    "license": "MPL-2.0",
    "repository": {
        "type": "git",
        "url": "https://github.com/deltachat/deltachat-core-rust.git"
    }
}

So there is no deltachat-rpc-server.exe? Do you perhaps have some antivirus program that false-flagged and quarantined it? Other possibility could be that the installer is broken and didn't extract it, but I think the former explanation is more likely

[WofWca]

Looks like Microsoft Defender started flagging deltachat-rpc-server.exe as Trojan:Win64/CobaltStrike.IM!MTB starting from 1.149.0.
See VirusTotal report: https://www.virustotal.com/gui/file/72e12e706136d86c9536e6fc8a2a67501bcdf9ca27a93d16d993ac92b0f3d42e

I don't know whether this causes both EAGAIN and ENOENT though. Update: looks like the original issue reports DC 1.46, which worked fine before, so the EAGAIN and ENOENT are either different issues, or it has to do with an update to Microsoft Defender signatures, which started flagging 1.46 as well.

Looks like Microsoft Defender started flagging deltachat-rpc-server.exe

This affects both portable and Setup.exe from here. Could have to do with the fact that they are not signed.

I opened deltachat/deltachat-core-rust#6338 in the core.

You're right. I closed the antivirus program and reinstalled Deltachat 1.48, deltachat-rpc-server.exe appeared in the folder.
My antivirus program prevented the installer from creating deltachat-rpc-server.exe .
Here's the log of Huorong Internet Security:

Now Deltachat can startup normally and works fine. Thank you very much!
