Random Critical Errors on most mod installs, Moguri Mod does not download at all

[ArcRiseGen132]

Currently I'm getting critical errors and the launcher crashing after the error is thrown after trying to download and install mods. However, its pretty random when it happens, sometimes it will let me download and install mods, other times it will crash.

Moguri Mod just does not download at all

I copy and pasted the error that pops up.

I'm running on Win11

I have no idea of what that error is. It might be related to the ZIP or RAR archive extraction.
You can try to bypass the problem by clicking on the mod's description: it will open the description in a larger window with the direct download link to the mod at the bottom, as shown in this screenshot:

Once you have downloaded the mod manually, you can drag-and-drop it on the Launcher to install it. Hopefully that will work better.

I just saw from your Reddit post that the issue is simply that you have an old version of Memoria.
Just update the tool with the latest release:

• latest official release there
• or beta-release there

EDIT: Nevermind. It's another person who posted a similar issue on reddit, my bad.

My version on the launcher is v2025.07.13 (changelog shows 07.04 though so im guessing its a mistake in the number being passed?)

I was able to download the mods I wanted after restarting the launcher a bunch of times and just hoping it wouldn't throw the error. Never got the Moguri Mod to download through the launcher though so I ended up doing a manual download for that.
