R语言内最近测试出现一个错误，不知是什么原因，请教

Error in exists(cacheKey, where = .rs.WorkingDataEnv, inherits = FALSE) :
invalid first argument
Error in assign(cacheKey, frame, .rs.CachedDataEnv) :
attempt to use zero-length variable name
本地用的R4.2.1；
单独给赋值时不会出现这种情况，有时候程序内运行着运行着出现这种问题，没看明白是什么意思。有遇到的大侠是怎么解决的吗？

让我想起来 R 社区里的一段智语，我贴一下。

The phrase "does not work" is not very helpful, it can mean quite a few things including:

Your computer exploded.

No explosion, but smoke is pouring out the back and microsoft's "NoSmoke" utility is not compatible with your power supply.

The computer stopped working.

The computer sits around on the couch all day eating chips and watching talk shows.

The computer has started picketing your house shouting catchy slogans and demanding better working conditions and an increase in memory.

Everything went dark and you cannot check the cables on the back of the computer because the lights are off due to the power outage.

R crashed, but the other programs are still working.

R gave an error message and stopped processing your code after running for a while.

R gave an error message without running any of your code (and is waiting for your next command).

R is still running your code and the time has exceeded your patience so you think it has hung.

R completed and returned a result, but also gave warnings.

R completed your command, but gave an incorrect answer.

R completed your command but the answer is different from what you expect (but is correct according to the documentation).

There are probably others. Running your code I think the answer is the last one.

确实如此。看着是有问题，实际结果一查，结果还是对的。但控制台就是给你了一个错误。

.rs.WorkingDataEnv看起来像是来自于rstudio的问题。

2023.06版出现的问题，可以尝试一下Daily build版本，看起来应该是已经修复了，release版的话应该是2023.08版本会包含这个修复。

另一个临时的办法是关闭数据框预览的功能

options(rstudio.help.showDataPreview = FALSE)

并重启R

就是的，很对，就是2023.06版本的Rstudio编辑器出现的。之前的版本还没碰到。

2023.06版本的Rstudio的数据框预览中，如果超过50列，上面点击向右查看超过50列的数据进行预览时，这个按钮不起作用。之前的版本可以。这个预览的功能是有点问题。

pfxy_ydir = pfxy_xdir = data.frame()
Error in exists(cacheKey, where = .rs.WorkingDataEnv, inherits = FALSE) :
invalid first argument
Error in assign(cacheKey, frame, .rs.CachedDataEnv) :
attempt to use zero-length variable name
在2023.06版本的Rstudio中连这个都会报错，而且是程序中间运行或测试中。一开始不会。运行着运行着就会。
