On Windows 10, I can reproduce the bug in LyX 2.4.3 and confirm that it 
is not there in 2.3.7. Just to be completely clear: I pasted Shuvo's 
align environment and code into a tex-code inset in a preview inset in 
new documents in both 2.4.3 and 2.3.7, saved the documents, and exported 
as plain latex to generate .tex files. I closed and deleted the lyx 
files, and then tried importing as plain latex the .tex files. 2.3.7 
worked, 2.4.3 didn't; screenshot attached.
