Extremely slow loading time - freezing at approx. 80%

I have been tinkenring for a week now. NO there is no workaround. Indeed , this one is a pretty nasty to diagnose beast… I finished using internal graphicas card ( intel 620 ) in low power mode ( Windows - Gaming - Graphics option ) . Totally uninstalled Hardware AMD RAdeon R7 M440 Graphiscs Card.
An so , an only so ,… the sim .loads without problems. I must say that I enjoy it very much , although performance is … you name it.
Fro what I have read so far in various sources and experimented myself, ther is a point opn the load process when a certain graphicas driver component "stops working and you are return to de desktop without further notices. I is NOT a CPU RAM problem . It is NOT a Graphicas card RAM problem. It is a SOFTWARE problem IMHO
Been simming and devolping windpows platform for 35+ years . All the way back to the XT 88 at 8 Mhz
and floppy disk drives.
