I have a similar issue when I had a IIA; it was easily solved by reversing backward about 10 foot. It's something to do with wind-up within the gearbox.
Red lever forward - yellow knob up - high range 2WD
Red lever forward - yellow knob down - high range 4WD
Red lever back - low range 4WD - (this is also needed to change out of high range 2WD)
The yellow knob position for Hi- range 4WD is usually with the spring below it nearly fully compressed.
If you have tried this with the red lever fully forward, and it has sprung back up again, there is probably shite inside the tin plate cover...

front of front output housing ,there are 3 shafts poke through, the red knob lever and 2 hidden behind a tin cover ,when you pull red back the others have to come forward through the housing ,these get seized through corrosion

Could be wind up but that's most likely if you've been driving on Tarmac for some time in 4wd.
The first cover is the double column one on the front of the box where the front prop comes out. There is a shaft that moves with the yellow lever, this can seize here. If it still can't be freed, the box might need to come off.

Spray the three shifts with wd40 or similiar and move high low lever two shafts should move middle one is 4wd lock when red lever is back this shaft should go backwards lift the lever in front of box that locks two wheel drive ,then move high low lever forward with latter lever lifted should hold middle shaft in place . If the offside shaft is not moving spray and gently tap the shaft end there is an internal Spring once it starts moving against Spring it will eventually pop out to the right position

when you pull the red one back does the outer one push out

Shaft info copied from another post I had elsewhere unfortunately photos have not copied across I had also posted on here but away so only using my phone .
"I have been taking some measurements of shaft positions as below.
high 2wd h/l 68mm 4wd lock 15mm 4wd shaft 27mm
High 4wd h/l 68mm 4wd lock 27mm 4wd shaft 51mm
Low 4wd h/l 44mm 4wd lock 15mm 4wd shaft 51mm
Nuetral h/l 44mm 4wd lock 15mm 4wd shaft 44mm"
So significant movement on shafts

rods are prone to come dislodged from the pivot
