'FFmpeg trying to concat two like videos but the timing is off

I am trying to concat two videos together using FFMPEG, but the output of the second video plays slow with no audio, but not only that, the time elapsed counter in the windows player counts slower as well. When I play it in VLC the timing is right but the audio is still missing.

For a better explanation of this effect please watch this video. Notice how slow the counter is

I know the videos have to be the same type and they are both 30 fps, mp4, same size, same tbn. Here is the ffprobe results. My goal is to make compilation videos using ffmpeg since it can combine videos very fast without re-rendering them. I get the videos from tiktok. Please let me know if I can clarify this anymore. Thanks

Video 1

>Stream #0:0[0x1](und): Video: h264 (High) (avc1 / 0x31637661), yuv420p(tv, smpte170m/bt470bg/smpte170m, progressive), 1024x576 [SAR 1:1 DAR 16:9], 622 kb/s, 30 fps, 30 tbr, 15360 tbn (default)

Video 2

>Stream #0:0[0x1](und): Video: h264 (High) (avc1 / 0x31637661), yuv420p(tv, bt709, progressive), 1024x576 [SAR 1:1 DAR 16:9], 760 kb/s, 30 fps, 30 tbr, 15360 tbn (default)

Output video

>Stream #0:0[0x1](und): Video: h264 (High) (avc1 / 0x31637661), yuv420p(tv, bt709, progressive), 1024x576 [SAR 1:1 DAR 16:9], 655 kb/s, 29.92 fps, 30 tbr, 15360 tbn (default)
