Hey @SimFG, I see that you are using go v1.19.*. Since v2.7 of wails, the minimum required version of go is 1.20 https://wails.io/changelog#changed. Try to bump your go version and see if it solves your issue.

@fkhadra Thanks your reply. In my computer, i have three go version environment, including 1.18, 1.19, 1.20. How do I can change the version that the wails uses.

@leaanthony How to change the go version in the output of wails doctor. I have changed the go.mod file. And when i use the wails dev -compiler go1.20, the app will also panic.

It's whatever is your system default.

I am using the latest wail version 2.9.1, and this problem still exists. This time I ensured that the go version is consistent and used version 1.21. Where can I see this crash log?
