What are the steps you made to build ?

[iDustbin]

Same issue on my site:
2x Terminal Windows:

1. step: yarn install
2. step: yarn run dev
3. step: yarn run app

App Windows seems to start and closes directly
Go Service is also running on my localhost
is there any Step by step installation guide available ?

Actually your Desktop app works with "Shopify" ?! i saied your whmcs integration,
could you help me here ?
Can't import the named export 'useState' from non EcmaScript module (only default export is available)

i added a few packages manually:
for example:

yarn add bufferutil
yarn add utf-8-validate

yarn add @vpnht/sdk seems to be broken ? shopify issues ?!
yarn check v1.22.10
