Compiler issue

[Alexz99-developer]

I started to have compiling issues after updating couple of my boards. So, I upload a sketch and it says "Exit status -1073741819. Error compiling for board ATmega16"(I'll use ATmega16 for demonstration purpose) and I have to press upload from two to four times to get the sketch to finally compile and upload.

It occurs every time I switch boards like Arduino uno, esp8266, atmega16, etc., when I restart my PC, and when I change board stats like Flash size. Like something is broken. Why am I getting this issue?

Please do this:

1. File > Preferences > Show verbose output during: > compilation (check) > OK
2. Sketch > Verify/Compile
3. After the compilation fails you'll see a button on the right side of the orange bar "Copy error messages". Click that button.
4. Paste the error messages in a reply here using code fencing.

I don't know how to use code fencing. But here:

Hi @AlexZ1999 ,
it looks like a Windows10 filesystem error (https://answers.microsoft.com/en-us/windows/forum/all/file-error-1073740791/23a0441b-f182-41f7-a6d3-cab3620e1919) . Try running sfc /scannow in an Admin command shell to try fixing the filesystem.
However, it doesn't look like an Arduino issue, so I'm going to close the issue, please reopen if necessary.
