Ren'Py Help with RenPy scripts end tags

[Dolmen]

Has anyone also experienced the problem that the end-tags ignore the back-slash? For example:
{i}xxxxx{\i} xxxx ### When behind it the text should be displayed normally, but it continues in italic and the same for {\b}
Or with: {size=+5}xxxxx{\size} #### the error message appears:

While processing text tag {size} in u'{size=+5}Hello, Jasmine xxxxx{size}'.:
File "game/script.rpy", line 658, in script
"{size=+5}Hello, Jasmine xxxxx{\size}"
Exception: empty value supplied for tag u'size'

In the first line the back-slash is not displayed at all, although it is there again in the full traceback.
Also here at F95 in the code input it is ignored from my side, because the [\CODE] not ended.
Is it maybe because of my operating system? I would be very grateful for a tip.

When closing tags, you need to use a forward slash (/).
A backslash is an escape character.

Very, very thanks, ThiccStudios!
How in the world did I come up with the backslash and not notice it?!
I've been writing the end tags with forward slash for years and on this project I just didn't recognize it! Of course I went to RenPy's site and looked at it, but even there I just didn't recognize my confusion!
Thanks!

No problem, sometimes we just can’t see the woods for the trees.

You got to the point! As I correct the many errors, I notice that I have a lot of \"xxxx\" in the beginning and was certainly thereby fasch led... THX
