Hi~When I tried to use framegrabber without Editor-mode, the program crashed. The crash report was something like these:

Have you tested the code without Editor-mode? Thank you very much if you could give me any help~
Hi,
Can you please provide another example that compiled in UE4.26/7?
Thanks
Hi~Is that possible to change the viewport of framegrabber? For example, I have many cameras and I wish to change the viewport in C++ code. Thanks in advance!
