Unable to unblock Add-on after crash

[gwburger]

I am developing a driver, and during a recent test made a mistake that caused SteamVR to crash. Previously, I would be able to go to Settings->Startup/Shutdown->Manage Add-ons to re-enable my driver, then restart SteamVR to get it to load again. Since updating SteamVR to 1.22.12, this no longer works. SteamVR 1.12.13 also has this issue. I can select the option to unblock and load my driver, but after resetting SteamVR the driver does not load, and the settings have been reverted back to blocking my driver.

Some steps that I have tried include:

• Deleting my driver, starting and closing SteamVR, then placing my driver back into the "SteamVR/drivers" folder
• Manually changing "config\steamvr.vrsettings", but this does not have any effect
• Deleting and re-installing SteamVR

The plugin works as expected if I place it onto a different PC that did not crash yet.

The problem is your driver, SteamVR goes into safe mode when one of the drivers crash, in your case it is most likely your driver segfaulting, SteamVR keeps going into safe mode and disabling addons because your driver keeps crashing on startup.

Also the "deleting my driver" part, don't do it like that, check the vrpathreg registry if it tries to load any additional drivers, verify the integrity of SteamVR files and never ever touch the drivers that are shipped with SteamVR.
