Windows 11 fails to Wake Up from Sleep mode

Hi

There is a similar post elsewhere in these boards but the suggestions there haven't fixed this for me.

I have a Samsung laptop with 11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80GHz 2.80 GHz, 16 GB RAM, (64-bit operating system, x64-based processor). 

Problem only started after I upgraded to Windows 11. It's fine if I remember to close the lid - and I've extended the sleep delay trigger to 20 mins which helps. But having to force a restart and lose all my tabs and docs each time I forget is really annoying! Any idea how to fix this problem? Thanks!
