encoder cant be found (before c2.avc used to work)

**Environment**
- OS: Windows, msi laptop
- scrcpy version: 2.4
- installation method: manual
- device model: huawei honor 10
- Android version: 10

so my issue is that lately it has not been able to open my mysccrpy file, and it seems like there is 2 abd devices trying to connect, and I dont know if its possible disable tcpip by default, because it is searching for usb and tcpip both

also it seems that I have to end adb process on laptop when it cant connect sometimes.

third is, i have used c2.avc encoder for long but it doesnt work currently, I dont know why, whenever I take it away, it works (with quite bad quality), and it shows to be available on list atleast,

if anyone can assist little, here is from console:

Start by reproducing the reported Windows scrcpy commands, especially --list-encoders and the uses of --encoder, then inspect the resulting ADB device list and encoder errors. Determine whether the report concerns the removed option, the unavailable encoder, or the offline TCP/IP device; done should clearly separate or resolve those behaviors with a focused reproduction.
