Win10 does not work "Alt+L" but works "Alt+Ctrl+L"

Good morning

As in the topic, I can't write Polish characters with the classic "Alt + letter", if I put "a" instead of "ą" for a letter, I get "a", for "L" I don't get "Ł" but just "L", etc.. I have to use "alt+ctrl+letter"
It's not always like that, it only happens once in a while at work. Today I was writing messages normally for 2 hours and suddenly it ended, when I wanted to finish the email to the client, I could only type Polish characters with the additional ctrl. I thought maybe it was a problem with my laptop, but recently my wife called me with the same problem, unfortunately I had no idea how to solve it. Of course I tried the ctrl+shift combination, nothing works.
The problem solves itself after some time (however, I can't wait at work) or after closing the browser (which is also a nuisance at work)
Do you know how I can switch back to normal spelling? In the attachment I send data about the laptop and the system

If possible, turn it off, uninstall all other keyboards and leave only the Polish-programmer and then you will never fall into such a trap by accident ... At least under older Windows it is possible, I don't know Windows 10 enough.

As you wrote, the problem solves itself after restarting the program under which we had such pranks, or only after restarting the entire computer ... If we want to continue writing quickly, we need to quickly save what we have created so far, turn off and turn on the computer again, and everything returns to normal, otherwise you won't quickly figure out what and how, but again, when we press an unknown keyboard combination, the problem returns, uninstalling keyboards other than the Polish programmer under Windows 7 removed this problem once and for all ... do you have keyboard shortcuts? Find such an option anywhere and try to fight by analogy with the right mouse button on foreign English languages, etc. can it be removed from this menu and give preference only to the Polish programmer ...
You also have the option to show the language change icon on the desktop bar but I don't know if the advanced mode on the desktop bar is then available, in Windows 7 there was also the advanced mode ... You also have the option "change language bar access keys" - take a look and quickly on the other hand, you can get there, but who would remember all the combinations...
Finally, turn off the computer and turn it on.
