League of Legends crashes at startup

Hey Gamers,
i am new to Linux, and new to Lutris also. I was playing League of Legends on Windows easyly, but on my Manjaro it crashes. The first time after installtion the client was starting correctly, could login after downloading all game updates, but i didnt even start a game, because i had no time. Next day not even the client start anymore.
my sytem:
Operating System: Manjaro Linux
KDE Plasma Version: 5.17.5
KDE Frameworks Version: 5.66.0
Qt Version: 5.14.1
Kernel Version: 5.4.18-1-MANJARO
OS Type: 64-bit
Processors: 1 × AMD Sempron™ 145 Processor
Memory: 1,9 GiB

When i enter…
lutris --submit-issue

…i stopped terminal at this point, because i didnt get prompt.

wine-versions activated are…

I also installed wine-lol-glibc and wine-lol from AUR, but i dont know where to choose them inside Lutris.

I recognized several problems, when i open wine console, then “cd games” and “dir”, it wont show the existing LOL-folder, but other game is displayed. Another problem, when i start winecfg, i have no desktop icon to launch game.

i used following command to end the cheat issue, i had before…
sudo sh -c ‘sysctl -w abi.vsyscall32=0’
=>this helped

In winecfg i also made some changes (as i should)
added libraries like
d3dx9_24 to 43, vcruntime 140, msvcp140, msvc120, vcomp140
under staging
Enable CSMT for better graphic performance - activated
under Graphics
1st bos checked and last boxed checked with entering my desktop resolution

This are a few infos about my system and my problem. If you need other information feel free to ask. Best when you also explain me the way to get the infos, because i already said i am kind of newbie. Btw i can also understand german.

Thanks in advance for your attention & help.

“Processors: 1 × AMD Sempron™ 145 Processor
Memory: 1,9 GiB” : how could you play with that ?

Your computer lack of memory, which could cause more bugs. You should really ad 2 more GB, it cost nothing …
And i’m pretty sure you have low fps with your Cpu. You could find a Phenom II from second hand for a very little price …
