bought a new desktop PC, re-installed OOTP 20...grfx are...weird?

I purchased a New Dell desktop PC (a Dell Inspiron 5090), newest video card, great machine. All my games (Steam, GOG,etc) run great,all settings maxed out and all grfx look great. Nothing weird graphically except with OOTP 20, modern 3D view.
PC specs:
Running WIN 10. Intel(R) Core(TM) i7-9700 CPU @ 3.00GHz (8 CPUs), ~3.0GHz. Direct X 12. NVIDIA® GeForce RTX™ 2060 SUPER 8GB GDDR6.
The issue with OOTP20: I reinstalled (Steam) OOTP 20, re-installed all the workshop stuff (historic BPs, facegens,etc). Now ALL left handed pitcher animations have the pitchers facing 2B in-game when they pitch (although the ball does travel to the plate), and the bats in the hand of LH batters appear on the ground in ANY visual (modern 3D) mode: batters box view or any other from-above view). This is disturbing and I can't change it. RH batters bats are fine and RH pitchers motions are fine.
I checked my older PC and everything in "Modern 3D" view is normal there. But not on my new PC. Everything else is fine with OOTP20 on my new PC, and all my other games have no abnormalities. JUST this game, and ONLY LH batters or pitchers, no matter WHAT stadium I play in (classic,historical, modern BPs; even game default-BPs). Any idea why?
I already wasted a LOT of time uninstalling and re-installing the game: same problem....and again: only on my new PC.
