'utf-8' codec can't decode byte 0xd0 error when using bulgarian

I get the following error trying to compile a file with bulgarian text on Ubuntu 20.04 with tex-live. I use kile to compile.

Traceback (most recent call last):
  File "/usr/bin/texliveonfly", line 360, in <module>
    (output, returnCode)  = compileTex()
  File "/usr/bin/texliveonfly", line 277, in compileTexDoc
    return readFromProcess(process)
  File "/usr/bin/texliveonfly", line 292, in readFromProcess
    line = getProcessLine()
  File "/usr/bin/texliveonfly", line 285, in <lambda>
    getProcessLine = lambda : frombytesifpy3(process.stdout.readline())
  File "/usr/bin/texliveonfly", line 44, in <lambda>
    frombytesifpy3 = lambda b = None : b.decode("UTF-8") if py3 and b != None else b
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd0 in position 19: invalid continuation byte

Minimum example:

\documentclass[a4paper]{report}
\usepackage[T2A,T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[english, bulgarian]{babel}

\begin{document}

\begin{enumerate}
 \item {\em Решение.} Тази стъпка използва компресираната и 
 факторизирана матрица от коефициенти на системата и дясната страна,
 за намиране на решението. Изчислителната сложност на тази стъпка 
 е $O(rn)$. 
\end{enumerate}

\end{document}

If I add an empty line between the \item row and the next, it compiles, but that adds an unwanted new paragraph and in the actual file I have other code that breaks it too.

I.e. if I change \item as below it will suddenly start compiling:

...
\begin{enumerate}
 \item {\em Решение.} Тази стъпка използва компресираната и 

 факторизирана матрица от коефициенти на системата и дясната страна,

\end{enumerate}

I am on Ubuntu 20.04.3 LTS with tex-live and have just upgraded from 18.04. On another computer with Ubuntu 20.04 same text compiles without a problem as a part of a bigger file.

I reproduced this issue with Italian as well.

Reproduced this with russian text on windows 11 machine fresh texlive installation. Can't compile my files :( anything I can do with this?

I stopped using it. The regular tex compilers work fine.

You can install all tex packages and then it will not complain about missing packages. They don't take that much space.
