Actual Behavior

I'm experiencing a recurring issue where Insomnia suddenly crashes while I'm using it and becomes unable to start again.

Reproduction Steps

The error happens intermittently, Insomnia works normally, then randomly stops and shows this error. After that, the app no longer loads; the only workaround is fully reinstalling Insomnia.

Is there an existing issue for this?
