This problem is caused by an incorrect calculation of the number of chunks in the read request.
Here is the workaround applied by the licensee :
int64 FSignedArchiveReader::PrecacheChunks(TArray<FSignedArchiveReader::FReadInfo>& Chunks, int64 Length, FEvent* Event)
{
SCOPE_SECONDS_ACCUMULATOR(STAT_SignedArchiveReader_PreCacheChunks);
// Request all the chunks that are needed to complete this read
int64 DataOffset;
int64 DestOffset = 0;
int32 FirstChunkIndex = CalculateChunkIndex(PakOffset);
int64 ChunkStartOffset = CalculateChunkOffset(PakOffset, DataOffset);
//int64 NumChunksForRequest = (DataOffset - ChunkStartOffset + Length) / FPakInfo::MaxChunkDataSize + 1;
int64 NumChunksForRequest = ((DataOffset - ChunkStartOffset + Length) + FPakInfo::MaxChunkDataSize - 1) / FPakInfo::MaxChunkDataSize; // workaround
1. Execute a read request whose end of the read request matches the 64KB chunk boundary.
Engine may report read requests beyond the end of Pak :
LogFileManager: Error: Requested read of 65536 bytes when 0 bytes remain (file=***.pak, size=9306112)
Then ensure condition failed occurs (see callstack)
