Disassembly view not working with JLink in Docker container
This error occurs when attempting to open the disassembly view.
Unable to disassemble: Error: Could not find an instruction at the baseAddress. Something is not right. Please report this problem: {"command":"disassemble","arguments":{"memoryReference":"0x000058c4","offset":0,"instructionOffset":-50,"instructionCount":50,"resolveSymbols":true},"type":"request","seq":25}
Debugging works as expected otherwise.
