I can't reproduce the issue.

I have the following library:

@Article{,
  title = {e1},
}

@Article{,
  title  = {e2},
  groups = {g1},
}

@Article{,
  title = {e3},
}

@Article{,
  title  = {e4},
  groups = {g2},
}

@Comment{jabref-meta: databaseType:bibtex;}

@Comment{jabref-meta: grouping:
0 AllEntriesGroup:;
1 SearchGroup:Not g1\;1\;groups != g1\;0\;0\;1\;\;\;\;;
1 StaticGroup:g1\;1\;0\;\;\;\;;
1 StaticGroup:g2\;1\;1\;\;\;\;;
}

Selected the group "Not g1".
Dragged entries into "g1".
The entries will either hidden or the background color will change if in the floating mode.
Switching to "g1" or "g2" did not cause any exceptions.

I am now on JabRef 5.16--2024-08-26--1620002 and will try to reproduce the exception. There isn't anything in the trace that I can decipher, so here are some details that could be important (guesses).

the library contains about 120 user-created groups plus a long list created by JabRef from the keywords field.
The groups and search groups associated with the exception were user-created.
The search groups include Boolean statements without regular expressions.
Group names include non-alphanumeric characters such as : and /, with ; as the separator
Most of the groups are nested one level deep.

Here are some examples.

2 StaticGroup::mygroup-001/example\;2\;1\;0xcd5865ff\;\;A static-group description\;;
3 SearchGroup:buyme\;2\;groups=:paywall and file!="" and groups!=/exclude\;0\;0\;1\;0x008000ff\;CURRENCY_USD\;A search-group description\;;
