Copy text from Version 4 to end of file directly from previous post.
Paste into new asc file using Notepad++
Note three line wraps near end of file with lines starting with 1.608E-12, MAX5492 and KF=1e-18
Position cursor at beginning of wrapped part and use backspace key to unwrap it.
Save file with no other changes. Schematic opens in LTSpice with no issues.
Start simulation and click on Vout. Note simulation speed of about 20us/s
Copy file to other computer running LTSpice 24.1.0
Schematic opens without issues.
Attempt to start simulation.
Log file opens with errors claiming issues with U1 - U10. BAS70L is not mentioned.
Close LTSpice.
Edit asc file with Notepad++ to remove only .ENDS (note that includes the dot) from BAS70L line. Save file.
Start simulation. Simulation runs at about 25us/s with no errors.
Stop simulation.
Note that log file opens claiming Simulation Failed when really it was just stopped. 24.0.12 doesn't do that.
Examine schematic more closely.
Find tiny extraneous piece of wire between R12/R28 and R10/C11. Remove it.
Cannot find any other schematic issues. U1 and everything else looks as intended to me.
Simulation still 25us/s
Post schematic file below as it is now on 24.1.0

I copied and pasted your file, and - after I'd sorted out the line wraps - turning off "Line Wrap" in Notepad made that a lot
easier, which was very useful advice - it run painlessly at about 25msec/sec.

It is running on LTSpice 17.0 on Windows 7, and I do have to download 17.1, which I'm going to do right now.
