Can't upload big file to Android Device

Hello! I recently faced an issue trying to upload big file to Android tablet. It doesn't detect with MTP so I tried to push it via ADB. But I get this error:

    
$ adb push myfile /sdcard
adb: error: 65544-byte write failed: Success

How can I fix it? Why is this happening? Storage space is enough:

EDIT: I want to use it for app devlopment, so I need ADB or quick MTP for app installing.

Is /sdcard really the correct path? Maybe try /storage/emulated/0? That's the internal storage
- Same error. Plus /sdcard is just symlink to /storage/emulated/0/
  
  Yeah but sometimes stuff like this works even if it seems to make no sense. If both of your devices are on the same wifi, maybe you can just use something to transfer it using that like KDE Connect. If you don't want to install anything, you could even try using SSH.
A little old skool maybe but why not try ftp?
- Would be my go-to as well. I'm using x-plore file manager on my phone to start an ftp server, and then push files via filezilla from my computer. Easy, and compatible with every OS out there.
Did you try LocalSend maybe?
- It works, but my Wi-Fi is very slow
  
  It'll be quicker than MTP because it's actually reliably consistent, unlike MTP.
  Since MTP is an unreliable hack, I've found using a "slow" wireless connection to work better.
- Yes, didn't help
File size?
- 197MB
  
  That's not much.
  Can you try copying that file via KDE Connect?
Does your PC actually see your phone via adb? What's the output of adb devices?
- Yes, I can even shell into it or pull/push small files
  
  How old is this phone? My guess is corruption at hardware level.
  If you can shell into it and have dd or something, try to write a simple file to e.g dd if=/dev/zero of=/sdcard/testfile bs=1MB count=200 If that fails when directly on the device, you can rule out network issues.
  You can also try downloading a file from the web that's about the size of your file or serving your file on the local WLAN with python3 -m http.server and accessing it on your phone. Just to see what happens.

I'd check the cable. Might be a POS that only works for the bare minimum of tasks.
