Have you tried the same landings with your Community folder completely empty?
Have you tried emptying both your rolling cache and your manual cache (which is advisable after any major update?
Have you tried disabling "damage to aircraft) in your settings to see if the same thing happens?
Does it happen only at one airport at at many?
Do not give up, there must be a reason. MSFS runs best if on a separate 1GB internal SSD if at all possible as the transfer speed is so much faster, I would try and avoid exterior HDs if possible.
Good luck!
