The launcher crashes when I try to enable mods

[Tamren]

This is not the game crashing, this is the launcher crashing when I click the “enable all” checkbox at the top of the mod list. If I click this the launcher instantly crashes.

However I figured out that if I go into the list of mods and individually tick each mod to activate it, the launcher works fine.

Steps to reproduce are:

1. Open list of mods, only the approved mods are checked.
2. I untick the “enable all” button at the top. This disables all mods.
3. I re-tick the enable all button which should enable all mods at once, this is what I normally do when I switch to mod realm.
4. The instant I tick the box the launcher crashes with the following message.

I found the cause. The crash appears to be related to the My Hero mod, clicking to enable it (or all mods) crashes the launcher.

This has happened before. Fatshark or the mod author of the Source Viewmodel mod removed it from the workshop without explanation. The mod remains on your list in the launcher and will cause it to crash, but to remove it you have to go to your subscriptions and manually unsub. You can only do it this way because the page for the mod no longer exists.

Instead of crashing the launcher should be capable of detecting invalid mods and removing them automatically, maybe with a message telling the player it has done so.
