@SuperDragonXD hi, may i know what is this FAQ for? the issues above is expected behaviour? Thanks.

[SuperDragonXD]

Not really expected behavior, but - since it's a very common issue, it has been added to the FAQ alongside a workaround.

[William150722]

@SuperDragonXD thanks for the reply, but I don't see any workaround inside the FAQ, or am I missed the document? Can provide the guidelines?

[SuperDragonXD]

The link that I added 3 months ago is outdated now. See this: https://lawnchair.app/faq/#adding-widgets-makes-lawnchair-crash

Hi @SuperDragonXD

Adding widgets makes Lawnchair crash This is a common issue (especially when the widget has a settings screen), and here's a temporary solution:

Change the default launcher to your system launcher. Open Lawnchair. Add the widget. Re-set Lawnchair as the default launcher. Unfortunately, there isn't a fix for this yet.

This above statement is temporary solution?

[SuperDragonXD]

Yes. There are many types of widget crashes and we still haven't fixed all of them.

@SuperDragonXD noted with thanks.
