D3DTexture2D import encode crashing with MFX_ERR_LOCK_MEMORY

I am developing a plugin for OBS Studio using libvpl for real-time coding. With the release of libvpl 2.10, textures for encoding were added and supported, it works, but I ran into a problem, after a few minutes the encoding process was interrupted with the error MFX_ERR_LOCK_MEMORY from the EncodeFrameAsync function. Further attempts to start encoding are immediately interrupted with the MFX_ERR_LOCK_MEMORY error until the application is restarted.

A step-by-step process that I'm doing:

1. A pool of intermediate textures is being created
2. Copying an external texture to pool
3. Importing textures from a pool to libvpl
4. Encode

The error occurs at stage 4. There are no errors in the first 3 stages. It is also worth clarifying that in my case the error occurs when encoding the 65537 frame.

The source code of the application can be found at the links below:
