I'm getting this error when I install the latest version. The updated version also doesnt show up in the Blender file explorer, where the previous versions of ZenUV do. In this case, I dragged and dropped ZenUV_5_0_3_0.zip over the viewport. I'm currently running Blender 5.0.1 https://cdn.discordapp.com/attachments/1480646935705555095/1480646935940694020/image.png?ex=69b06f6a&is=69af1dea&hm=bc1282aca482a44230f924f69e24c85f2b263c70b133c0ead02b620a8513d0dc&

We are currently fixing a bug in Zen UV 5.3.2, so we have temporarily reverted to the previous version, Zen UV 5.3.1. You can install it or wait for the fix. The fix will be ready in the next 24 hours. Read more here. https://discord.com/channels/695619708879372398/695620319741870150/1480620357315592343
