Permission Error Writing a file on Windows 10 & PHP 7.4

[teleclient]

The same error happens, no matter what the permissions are.
The same exact code works fine under Linux.

Exception: fwrite(): write of 8192 bytes failed with errno=13 Permission denied in BlockingFile.php:66

Previous TL trace:
exceptionErrorHandler()
BlockingFile.php(66): fwrite()
Files.php(1153): write()

I also have this problem, no solution yet?

Failed writing to file handle: fwrite(): write of 8192 bytes failed with errno=13 Permission denied

Does it work without amphp/file?

[valery-lavrik]

Oh sure. I tried to reproduce this example, it worked great
Can fopen() open in the wrong mode?

[kelunik]

Yes, maybe that's the case. How do you open the file?

[valery-lavrik]

I don't know, this is not my library. I just use it and find it breaks at this point. And I have no idea why ...

[valery-lavrik]

Can the developer of this library tell me?
@amphp-bot

[kelunik]

Not within the library, but rather how you use the library to open the file. Please post a full example to reproduce the issue.

Issue happens in \Amp\File\BlockingFile::write, which used in MadelineProto downloadTo* methods

I think trace should be like this:
