Audio Waveform gone every time i try importing a new track

I searched and searched and every solution i found was only temporary, and i am getting so. unbelievably. sick. of. it. every time i import a new audiotrack (.wav) into my project and try to use it on my timeline i get no waveform. the track works, audio works, but it just wont show me the waveform. i did all the usual suspects, "show waveform" ,"generate waveform", deleting cache usually does the trick but only when i delete - close programm - reopen, that just cant be the solution, i tried updating to the newest version, i tried deleting peakfiles from appdata, i tried mp3 tracks, i tried over rightclick -> import instead of drag and drop and im really getting sick of it happening over and over again, does anyone has a solid, longterm solution to this? i dont want to delete my cache every 5 minutes.
