VSTi stops producing sound after a while

i have been arranging with no issues using my PC - WIN 11 then suddenly this thing i have encountered really buffled me out… calling a vsti like example omnishphere, kontakt, keyscape produces sounds bu to some point stops but you can see midi is triggering via the meter. closing and re opening the vsti would sound again but would stop producing again the sound after a few seconds, even if im not playing with it and just calling it would stop to produce sound, but other instruments like pianoteq, addictive drums never gave such problems. pls help… it use to run normally as it is, nut the past few weeks i encountered such problem.
