hello everyone, I'm just asking is there an indoor gps? since I going to make a gps tracker for vehicle with using arduino, I bought a gps module but it cannot get the signal if I use inside of my house which is I think it will also not works on inside of vehicle

No. GPS needs unobstructed line of sight to multiple GPS satellites in orbit.
The systems mentioned in @kolaha post refer to approximations obtained by locating other devices and compiling lines of bearing using signal properties. Apple does this with "locate my phone" and "air tags" when GPS is not available.

Pozyx (among others) makes commercial indoor positioning systems, and offers an Arduino-compatible version, all using fixed beacons replacing the satellites of the GPS system.
Expensive, though, and you can DIY one for less, with these UWB modules, and these example programs on Github.

You can buy GPS modules with external antennas. The GPS can be indoors, but the antenna must be outdoors, with a clear view of the sky.
Your description does not indicate a problem with the IDE and hence has been moved to a more suitable location on the forum.
Try it in the vehicle and see what happens. Glass doesn’t seem to block the signal, so you may get good position depending on where the GPS is located.
Consider too that mobile phones generally have GPS and that mostly works in a vehicle.
Anecdotally, around where I live, there is good position much of the time but it cuts out if there are too many trees lining the road. Tall buildings might well have a similar effect if there were any.
My NEO6-M and UNO works from inside my apartment, inside the car, inside the trains I drive. The NEO6-M has a 1 inch square antenna.
You can use an outside aerial for your gps or try mounting the aerial on the inside of the windscreen .( sat nav’s work in the car !)
I guess inside your house , then you know where you are lol
