The new execute command, which could be used by turning on "experimental toggle" prior to 1.19.50, has stopped working under certain conditions since 1.19.50 with an error.

Conditions:

• Written before 1.19.50
• No updates have been made since the 1.19.50 update.

In the command block where this bug occurs, the error will disappear and the command will work if the following steps are taken.

Steps:
1. open the command block in question
2. type a letter and close it.
3. delete one character typed at random
4. it will work as usual

Notes:
This bug affects mainly mini-game servers and other servers that have taken measures against the new execute command. It is very labor intensive and requires a lot of work, as every command has to go through the bug removal process.
